I'm having trouble with the following:

Inputs x 1, 2, 3, ?

Outputs y 0, 2, 6, ?

I have tried everything and can't come up with the equation. Please help! Also, if you have any tips on how to solve that would be great. Thanks!

Since you have only 3 cases, that gives very little to go by, but

0 = 0x1

2 = 1x2

3 = 2x3

from the given I would guess at

f(x) = x(x+1) or x^2 + x
