72 goddamn people.

The answer is fucking 9.
2 does not equal 6, 3 does not equal 12, etc.
It doesn't matter how many wrong solutions are written above the problem, 9=9

2*2+2=6
3*3+3=12
4*4+4=20
5*5+5=30
6*6+6=42
9*9+9=90
N=a*a+a

Only for geniuses? for real? This shit is basic

Why does everyone always make it more complicated than it has to be?
2*3=6
3*4=12
4*5=20
5*6=30
6*7=42
Therefore 9*10=90

WHOAH! Outside of the size constraints 0 < gamma(?) < 1 and t > 0, I can actually solve that. Calculus based physics is teaching me things!

tree fiddy

Based on the calculations/numerical statements:

y= x * (x+1)

x = 9

y = 9 * (9+1)
y = 9*10
y = 90

OP here. I've only done undergrad math work as an EE major. I don't know those fancy gamma functions and whatnot

2×3=6
3×4=12
4×5=20
5×6=30
6×7=42
7×8=56
8×9=72
9×10=90
9=90 Dumbasses. Follow the trend.

Γ(z) is valid for z∈ℂ\{0, -1, -2, -3, ...}. The constraints are for the contour of integration and the locations of the poles of the integrand.

6 +6 = 12
12 + 8 = 20
20 + 10 =30
30 + 12 = 42
42 + 14 = 56
56 + 16 =72
72 + 18 =90

This la how it goes. 6-8-10-12-14-16-18 so 9 = 90
Easy but nice

ah, overlooked something....

Without any given rule to follow the concideration of a possible formula belongs to the person itself. Therefore any number may be the right one

If 2=6 6=2 not 42

fist answer is best.also correct but really asshole answer lol

That is undergrad math.

90

this tho.

Upside down 2

As an EE, I only took the basic calc up to diffy q's

That would make sense for EE, so I see your point.

Agree

It's a little simpler than that
2*3=6
3*4=12
4*5=20
5*6=30
6*7=42
9*10=90

The answer is 90. The pattern is n = n(n + 1).

/thread

Or N=a*(a+1)

Now that I can do, but I'm too lazy. Something like let u=that stuff in ln, and then IBP. Maybe some trig subs. It's summer man

Thr numvers on the left could be shorthand for saying 1st in the sequence, 2nd, etc...

You could even just figure out the pattern
2*3=6
3*4=12
4*5=20
5*6=30
6*7=42 therfore following the pattern 9*10=90

even simpler
0 + 6 = 12
12+ 8 = 20
20+10= 30
30+12= 42
42+14= 56
56+16= 72
72+18= 90

You almost have the first substitution right but trig subs aren't the next step.

90 you cunt

That is definitely not simpler. It also has no relation to the actual question.

>Saying /thread when you can't even do basic math

KYS faggot

72 or 90 and that is why this is bait.

NERDS

OP here. The answer is 90

Tricky bastard

The answer is 58. Thanks for admitting I am a genius OP

Well I may not know enough math to do this. Looking at the w|a solution, I don't recognize this Li function

wolframalpha.com/input/?i=integrate sqrt((1-t )/ (1+t)) * log(sqrt((1-t )/ (1+t)))

OP here. You have officially earned this badge of honor.

This goes for anyone saying the answer is 72 as well

You don't have to compute the indefinite integral to do these. Li₂(s) is the dilogarithm and there are simpler ways to do the integral (and in general the whole class of integrals) than using it.

Wait it's a cube root? The other image had a square root

90. It isn't hard, retards

It's a square root in the other image. The two integrals I just posted are different than the previous two I posted, but they are of the same type.

An = n(n+1)
A9 = 9*10
A9 = 90

90

9*10

1/3
1/4
1/5
1/6
1/7
1/8
1/9
1/10

Im going with 75, what say you OP?

MUSLIMS DID GERMAN MASS SHOOTING

Wow, you morons now how to make shit difficult. The right column is inreasing by 2 ie; 6,8,10,12 etc. now if you can't do simple edition, this is truely a place for faggots

That's how I figured it out as well, some people took the fucking hard way it seems

Also, fucking store fronts every godamn time!

2 - 6
3 - 12
4 - 20
5 - 30
6 - 42
7 - 56
8 - 72
9 - 90
