Hey everyone, I'm new here. I've taken a few classes which dealt with proofs by induction, and recently a friend came to me for help with one. I'm so rusty now though, but I know it should not be hard. The problem is to show that the solution to x-sub-n+1 = r (x-sub-n) is x-sub-n = r^n(x-sub-zero). Can anyone help solve this?
