Stuck on this proof...any help is appreciated. Here is what I have thus far.
Suppose n is odd, then n = 2j + 1 for some integers j, k, and m. then m(2j + 1) = 2jm + m. Since the product of two integers is an integer, let k= jm. => 2k + m
I'm sure I'm just not seeing some algebraic trickery here. Thx!
