F1 f3 f5 f2n − 1 f2n
Problem 3.64: Let f1,f2,f3,... be the Fibonacci numbers. Prove by induction that for each natural number n: a) f1 + f3 + f5 + ··· + f2n−1 = f2n. ,Trying to prove: F2 + F4 + ···F2n = F2n+1 − 1. We know F3 = F2 + F1. So, rewriting this a little: F2 = F3 − F1. Also: we know F5 = F4 + F3.
