yfw it's 90

Took all of my 3 fingers to solve this.

[–]theblaah [スコア非表示]  (1子コメント)

only for geniuses

grade school level math

[–]rock_callahan [スコア非表示]  (0子コメント)

Yeah, i am literally the worst ever at math. I got something like 17% in my mid year of highschool before i was allowed to drop it.

And i got 90 in fucking 5 seconds flat. If by genius they mean short yellow bus riders, then yeah.

2=6

But thats wrong you fucking fag

[–]Georgey22 [スコア非表示]  (3子コメント)

No it's not you autistic robot. if >2=6 then the two are obviously in different units....

[–]Kerai [スコア非表示]  (1子コメント)

You can't ommit units. If they are unknown, you write it as 2x = 6y, you autistic fag.

[–]Georgey22 [スコア非表示]  (0子コメント)

You don't know anything about math. It isn't proper but it isn't wrong. Only nonmath newfags like you would call it wrong.

[–]ltsmiles/k/ommando[S] [スコア非表示]  (43子コメント)

For normies too autistic to do math:

2*3=6

3*4=12

4*5=20

5*6=30

6*7=42

9*10=90

x=x*(x+1)

[–]Bananeurd [スコア非表示]  (0子コメント)

math is their specialty, don't ruin this for them

[–]iwatags[🍰] [スコア非表示]  (0子コメント)

he thought it was recursive like fibonacci. f(x) <==> f(x-1) + x*2

[–]n1ckbrx [スコア非表示]  (5子コメント)

there is another way.

22 +2=6

32 +3=12

42 +4=20

52 +5=30

62 +6=42

92 +9=90

no need to include any numbers that are not given.

Correct solution

I win.

Edit: people further down beat me to it.

[–]taxintoxin/sci/duck [スコア非表示]  (1子コメント)

That's the same damn thing.

x*(x+1)

(1+x)*x

x+x2

fuck formatting

[–]n1ckbrx [スコア非表示]  (0子コメント)

Yes it is, didn't see that at first! Sweet maths bro!

[–]ToThePint [スコア非表示]  (0子コメント)

I thought of it this way;

2: 6
3: 12 (diff 6)
4: 20 (diff 8)
5: 30 (diff 10)
6: 42 (diff 12)
7: 56 (diff 14)
8: 72 (diff 16)
9: 90 (diff 18)

Again, probably the same result and equation overall as everyone else.

[–]Beanies [スコア非表示]  (23子コメント)

Did you just say x = x*(x+1)??????????????

Are you sure you're the one who doesn't know how math works????

[–]S00rabh [スコア非表示]  (10子コメント)

That's how programming works.

X++; Or X=X+1; is valid.

In code world, '=' means value to be assigned and '==' means checking for equal value.

[–]telehax [スコア非表示]  (4子コメント)

why would you store the value to x again if you're programming though, are you limited to only one variable?

[–]uptotwentycharacters/lgbt/ [スコア非表示]  (0子コメント)

Sometimes you might want to keep it to one variable if you're keeping track of a changing quantity, using multiple variables would just confuse things. For example, if you have a variable X representing your money, you start out with $1000 dollars so X = 1000. Then you find 250 dollars, so you'd write X = X + 250, which means "take the old value of X, add 250 to it, and then store that value of X." It's kind of like opening a text document, editing it, and then saving it under the same name, overwriting the old version.

[–]abstraakt [スコア非表示]  (0子コメント)

don't worry about it unless you wanna program

[–]zennaque [スコア非表示]  (0子コメント)

Because you don't know how many times you want to use it. You don't auto generate variables infinitely, you reuse a few you define again and again.

In this case though you don't really have a reason to store the answer, you'd just display x*(x+1) rather than store it anywhere.

[–]S00rabh [スコア非表示]  (0子コメント)

We are not limited to one variable but what if you want to increase the value of some integer and then use it again.

Ex: x = 7; \i have give vale of 7 to x

Display x on screen; \Display 7 on screen

Increase values of x = x+1; \x=8 now

Display x on screen; \Diapay 8

With your logic we will have to use new char(x,y,z) for every increment. Here we can just increase the value of x and still reuse it in future code.

[–]Beanies [スコア非表示]  (3子コメント)

x=x+1 is only valid in terms of coding because it overwrites the variable X with X+1,

In terms of math, that equation cannot be.

[–]uptotwentycharacters/lgbt/ [スコア非表示]  (2子コメント)

Yeah a key difference between math and coding is that with coding there is a sort of time element as the program runs through the code, whereas math is static with respect to time.

[–]Assaultistheshit [スコア非表示]  (1子コメント)

No, it's more that in math you're representing a mathematical statement with y=mx+b. You're saying the left side must equal the right side. In code, it's just a set of instructions. y=mx+b: Take the value in mx, add it to the value in b, store that value in y.

The analog in code would be x == x+1 which of course would never be true.

[–]uptotwentycharacters/lgbt/ [スコア非表示]  (0子コメント)

Yeah that's pretty much what I'm saying. In math, '=' basically means 'is equal to'. In coding, '=' means 'make equal to'. The first is just a statement of fact, the second is an order to do something.

    [–]Beanies [スコア非表示]  (2子コメント)

    x = x2 + x is what the equation would equal if you expanded it.

    If an equation doesn't contain any type of constants, then the answer will always be 0. You're right that it isn't invalid because there is an answer that satisfies the equation.

    You lucky this time nigga

      [–]kp33ze [スコア非表示]  (12子コメント)

      For those equations to actually be valid... f(2)=6 f(3)=12 f(4)=20... And so one

      2 cannot equal 6. Mathematically those equations make no sense.

      [–]ltsmiles/k/ommando[S] [スコア非表示]  (3子コメント)

      Ok, lets say the whole left side of numbers is x, and the numbers it is multiplied by is y. Y increases by 1 after each multiplication. Therefore: 2*3=6, so after y increases, it will be 4, and the next number is mutlipled by 4.

      [–]Odds-Bodkins [スコア非表示]  (2子コメント)

      he gets it. no mathematician would write "2=6".

      [–]uptotwentycharacters/lgbt/ [スコア非表示]  (1子コメント)

      Yeah, it's improper notation. A mathematician would use something like function notation: f(2) = 6, f(3) = 12, and so on.

      [–]AdamDemampTopGun [スコア非表示]  (0子コメント)

      Correct. As soon as you see 2=6, there is no answer. The question is based on a false premise.

      [–]TheRealF0xEwee/a/boo [スコア非表示]  (3子コメント)

      2=6 2 * 2 + 2 = 4

      3=12 3 * 3 + 3 = 12

      4 = 20 4 * 4 + 4 = 20

      5 = 30 5 * 5 + 5 = 30

      6 = 42 6 * 6 + 6 = 42

      7 = 56 7 * 7 + 7 = 56

      8 = 72 8 * 8 + 8 = 72

      9 = 90 9 * 9 + 9 = 90

      [–]Quadrupol [スコア非表示]  (4子コメント)

      Isn't it just (x2 )+x. (9*9)+9=90

      [–]Iguessilltryit [スコア非表示]  (3子コメント)

      x(x+1) = (x2 )+x

      [–]gallolala [スコア非表示]  (2子コメント)

      But that is the same equation, just worded differently

      [–]Iguessilltryit [スコア非表示]  (1子コメント)

      That was my point. People are answering with both equations, i just wanted to show that they were the same with the exception of one being more expanded than the other.

      [–]gallolala [スコア非表示]  (0子コメント)

      Huh. Got it by determining 11 = E, 19 = T from the three-letter words. Then for the rest I found a website allowing me to search a dictionary with regexes and picked what was most likely.

      Except for porks. I just had no idea what to put there.

      Nth term equation for sequence: n2 + n
      Put value in equation (this scenario is n=9)
      92 + 9
      =90

      [–]OhMoscow [スコア非表示]  (3子コメント)

      You multiply the number by itself.

      9 x 9 = 81

      Then add the number to the product

      91 + 9 = 90.

      3 x 3 = 9

      9+3 = 12

      All of them work this way

      [–]Easy_Money470/fit/izen [スコア非表示]  (0子コメント)

      It's literally just an easy fucking function, you autistic faggots.

      x*(x+1)=y

      Maybe I'm missing something here, but these questions to test your intelligence are always stupidly easy.

      [–]firehead818 [スコア非表示]  (0子コメント)

      It's so easy.. you don'tneed a program to solve it. Pay attention.

      2 * 3 = 6

      3 * 4 = 12

      4 * 5 = 20

      5* 6 = 30

      6 * 7 = 42

      It's just incrementing what you multiply the number by 1.By this logic...

      7 * 8 = 56

      8 * 9 = 72

      9 * 10 = 90

      alternatively...

      x(x+1) = y

      function is x2 +x so answer is 90

      [–]uptotwentycharacters/lgbt/ [スコア非表示]  (2子コメント)

      It's 56. The rate of change goes up by 2 each time. 6 + 6 = 12, 12 + 8 = 20, 20 + 10 = 30, and so on.

      Edit: Oh wait, didn't realize it was asking for the result of 9 rather than 7. The pattern would continue as 7 = 56, 8 = 72, 9 = 90.

      [–]Mugii [スコア非表示]  (0子コメント)

      You don't need a fucking equation you retards. You add 6 then 8 then 10 then 12 then 14 then 16 then 18. Keep your autism to a minimum holy shit

      90

      [–]Eoiny [スコア非表示]  (2子コメント)

      First line is 2 (x 3) = 6, 3 (x 4) = 12, 4 (x 5) = 20, 5 (x 6) = 30, 6 (x 7) = 42... Oh right, I missed the skip from six to nine and multiplied nine by eight. It should be nine by one higher than nine, which is 9 x 10. Apologies, you are correct.

      [–]Duckshunz/fit/ [スコア非表示]  (1子コメント)

      I did the same thing, but I saw someone else wrote 90 so I took another look at the question

      [–]BillyDiesInTheEnd [スコア非表示]  (0子コメント)

      It could be that you multiply by the next number in the series.

      Therefore, its n(1+n)= tn

      9(1+9)= 90

      [–]Wiezzenger [スコア非表示]  (2子コメント)

      say it's y = x, are you saying that it's y_2 = x_1+2*y_2?

      [–]SkeeballMcGee [スコア非表示]  (1子コメント)

      Shit man, I'm not good at math. I'm great at other stuff. All I did was say if 2 = 6 and 3 = 12, which is (3x2)+6 (since 6 was what 2 was equal to) It looks like it works for everything else on the list. The next one is 4 = 20, (4x2)+12 since 12 was what 3 was equal to, and just follow that up. I know I'm not wrong, it's just different from all the other answers.

      [–]SkeeballMcGee [スコア非表示]  (0子コメント)

      Nope, got it wrong, I fucked up at the 7, I end up with 90. It seems I may actually be retarded. I took a weird way to come up with some shit that could easily just be multiplying the number with a number one higher than itself.
