F n f n−1 +f n−2 if n 1 in python

WebFinal answer. Problem 1. Consider the Fibonacci numbers, define recursively by F 0 = 0,F 1 = 1, and F n = F n−1 + F n−2 for all n ≥ 2; so the first few terms are 0,1,1,2,3,5,8,13,⋯. For all n ≥ 2, define the rational number rn by the fraction F n−1F n; so the first few terms are 11, 12, 23, 35, 58,⋯ (a) (5 pts) Prove that for all ...
