I'm working on solving a recurrence relation for my discrete math class, and am running into a dead end at the step I thought would be easiest. I've come up with the equation: A(sub)n = (A(sub)0 – p/a)(1+a)^n+p/a All I need to do now is solve for p, but it's been a while since I took algebra, so no matter which route I take I run into a dead end. Any help would be greatly appreciated!

A(sub)n = (A(sub)0 – p/a)(1+a)^n+p/a A(sub)n= A(sub)n = (A(sub)0)(1+a)^n – (p/a)(1+a)^n+p/a Now find a common factor of p and solve.
