**Quidditch**, Friday, September 19, 2008 at 12:28pm3 - 8 difference = 5

4 - 11 difference = 7

5 - 14 difference = 9

etc.

In each case the difference is:

2 x (first number) - 1

- Help! -
**Quidditch**, Friday, September 19, 2008 at 12:32pmLet x = first number

Let y = second number

x +(2x-1) = y

3x-1=y

so

x = (y+1)/3
