1. The problem statement, all variables and given/known data Prove if n is an odd integer then n^2 - 1 is divisible by 8 3. The attempt at a solution I already set up the whole inductive step and everything but I am trying to prove it works for n+1, here is what I have so far... n=2k+1 ((2k+1)+1)^2 - 1 = 4k^2 + 8k + 3 = 8m Where k and m are arbitrary integers. What do I do from here to get it in the form 8m? I can't figure it out.
