60

square + add self

90

90, considering the next one is 10.

Your honework is done OP go to sleep

90

[spoiler]72[/spoiler]

I guess this is a psychological test.

My first answer was 72, then I saw the people replying 90 and went back and saw why I was wrong.

Can you post a link to the analysis?

>I got it wrong
>that means it's a trick psychological experiment

The answer is 72 though

[math]1^2+1,2^2+2,3^2+3,...,n^2+n[/math]

60 if you jump straight from 6 to 9


90 if you up include 7 and 8

i added the next number times 2

Didn't notice the skip in numbers.

n*(n+1) works too though

that's just n^2+n factored

Well OP, I gotta tell you this was a tough problem... for a while, I was stumped! But then I realized that this is clearly a logarithmic growth. So I made a regression to find the line of best fit. And the answer I arrived to was that the value for x=9 is about 50.

aww yeah x^2 + x is x(x-1) i like it i like it

>That one guy
I love you

yeah factoring is pretty cool

It should be x(x+1)

holy shit sorry im high af

You just follow your rational mind =.=

No, the picture is clearly designed to test comprehension, not math. The math is simple. The skip in numbers is not a math challenge.

how do you get 72

the only patterns i can find all end up at 90

f''(x)=2
f'(2)=5
f (2)=6
f'''(x) and up = 0
T (x) = 6 + 5*(x-2) + (2/2)*(x-2)^2
T (x) = 6 + 5*(x-2) + (x-2)^2
T (x) = x + x^2

Isn't this just [ x * (x + 1) ]?

So 90

56

That clearly makes no sense. 2 cannot ever equal 6 no matter what you do. This is silly.

2*3

9*10

Number of arrangements of [math]n[/math] indistinguishable balls in [math]n[/math] boxes with the maximum number of balls in any box equal to [math]n-1.[/math]

>thinking he's smart for using intuition on a kiddy level problem
Good luck getting anywhere real with that

Lrn2functional-notation fgt pls

30+2*6=42
42+2*7=56
56+2*8=72
72+2*9=90

>doesn't have any mathematical intuition

Are you the guy that couldn't answer the question without showing all his work?

2*3 = 6
3*4 = 12
4*5 = 20
5*6 = 30
6*7 = 42
7*8 = 56
8*9 = 72
9*10 = 90

[math]n*{n+1} = x[/math]

the factor always gets one bigger
2x3=6
3x4=12
4x5=20

etc.

you're missing some parenthesis' there friend

False
False
False
False
False
9

kek'd

real answer

What do I win?

No its 90, it would be 72 only if you stopped at 8.
