Web$\begingroup$ I think you've got it, but it could also help to express n in terms of an integer m: n = 2m (for even n), n = 2m+1 for odd n. Then you can use induction on m: so for even n, n+2 = 2(m + 1), and for odd n, n+2 = 2(m+1) + 1. WebProve that ∑ i = 0 n F i = F n + 2 − 1 for all n ≥ 0. I am stuck though on the way to prove this statement of fibonacci numbers by induction : my steps: definition: The Hypothesis is: ∑ i = 0 n F i = F n + 2 − 1 for all n > 1 Base case: n = 2

WebThe natural induction argument goes as follows: F ( n + 1) = F ( n) + F ( n − 1) ≤ a b n + a b n − 1 = a b n − 1 ( b + 1) This argument will work iff b + 1 ≤ b 2 (and this happens exactly when b ≥ ϕ ). So, in your case, you can take a = 1 and you only have to check that b + 1 ≤ b 2 for b = 2, which is immediate.
