Hi
I need some help with the following problem:
1. Find all functions f: Z+ -> Z+ such that for each n Є Z+ we have f(n) > 1 and
f(n + 3)f(n + 2) = f(n + 1) + f(n) + 18
2. I've been reading everywhere and I can't seem to find anything like this. I was wondering if anybody knew where to start
3. I was thinking of trying one to one, but it doesn't make sense. Then induction but I don't think I can conclude anything from that either.
Thanks for your help
