I have the following sets:

x | 6 |  8 |  10 |  12 |  14 ...   y | 4 |  5 |  6  |  7  |  8  ... 

I need to find the value of y given any positive value of x.

I know it sounds simple, but I seem to have drawn a complete blank on this one :/

Cheers

    This is most certainly unfitting to the set theory tag.2011-03-30

If the ... means you increase x by 2 each step and y by 1, then $x=2y-2$ and $y=x/2+1$
