90 i think

2x3
3x4
4x5
5x6
6x7
7x8
8x9
9x10

7 = 42 + 14
8 = (42 + 14) + 16
9 = ((42 + 14) + 16) + 18

If you do either one of these the answer is 90.

9x7 = 63 Ya'll not tricking me.

why are you multiplying 9 & 7?

 

[beanz]

x = (y/x) - 1
x^2 = y - x
x^2 + x = y
f(x) = x^2 + x

f(2) = 6
f(3) = 12
f(4) = 20
f(5) = 30
f(6) = 42
f(7) = 56
f(8) = 72
f(9) = 90

Here it is in c++

int my_function( int x )
{
  int y = 0 ;

  y = exp( x, 2 ) + x ;

  return y ;
}

The answer is 90.

Here it is in c++

int my_function( int x )
{
  int y = 0 ;

  y = exp( x, 2 ) + x ;

  return y ;
}

lol at calling a function and creating variable y when all you need is:

int my_function(int x) {
    return x * x + x;
}

 

[PikaDaDon]

lol at calling a function and creating variable y when all you need is:

int my_function(int x) {
    return x * x [COLOR=#ff0000][B]+ x;[/B][/COLOR]
}

I wrote it like that for readability and simplicity. But yeah, my way would be considered 'slower' (for something like game development where performance matters) due to the function call (exp) and temporary variable (y).

90 lol geniuses. good luck in life yall


*edit* people writing this in code yeah...i can do that too


i'm guessing they're saying it's for geniuses and its not 63 because you need to make that leap when your mind thinks it's on a roll

 

[jeh]

56...

x = (y/x) - 1
x^2 = y - x
x^2 + x = y
f(x) = x^2 + x

f(2) = 6
f(3) = 12
f(4) = 20
f(5) = 30
f(6) = 42
f(7) = 56
f(8) = 72
f(9) = 90

@beanz
In simplistic terms, X is the number on the left in (), and Y is the number on the right.
So using 8:

8(squared) = 72 - 8
64 = 64

Or

8(squared) + 8 = 72
64 + 8 = 72

Or

8 = 8(squared) + 8
8 = 64 + 8
8 = 72

 

[ThatTruth777]

using y = 1.7366x^1.771, I got.... 85.048

 

[Ethnic Cleansing]

90
