Define the fibonacci numbers by f(0) = 0; f(1) = 1; and then recursively for natural numbers n ≥ 2 by f(n) = f(n-1) + f(n-2). a) Write out the first 7 fibonacci numbers. I b) Make a conjecture about which numbers n will give us that f(n) will be an even number. c) Prove an exact characterization of these numbers using strong induction. (i.e. show that if your characterization is true up to some point, then it would be true just after that)
