20. The Fibonacci numbers start with Fo 0, F1 1 , 1, F2 etc: 0,1,1,2,3,5,8,13,21,34,55,89, 144, 233,377,... Show tha...
Exercise 6. Let En be the sequence of Fibonacci numbers: Fo = 0, F1 = 1, and Fn+2 = Fn+1 + Fn for all natural numbers n. For example, F2 = Fi + Fo=1+0=1 and F3 = F2 + F1 = 1+1 = 2. Prove that Fn = Fla" – BM) for all natural numbers n, where 1 + a=1+ V5 B-1-15 =- 2 Hint: Use strong induction. Notice that a +1 = a and +1 = B2!
(5) Fibonacci sequences in groups. The Fibonacci numbers Fn are defined recursively by Fo 0, F1 -1, and Fn - Fn-1+Fn-2 forn 2 2. The definition of this sequence only depends on a binary operation. Since every group comes with a binary operation, we can define Fibonacci- type sequences in any group. Let G be a group, and define the sequence {fn in G as follows: Let ao, a1 be elements of G, and define fo-ao, fi-a1, and fn-an-1an-2 forn...

Let f0, f1, f2, . . . be the Fibonacci sequence defined as f0 = 0, f1 = 1, and for every k > 1, fk = fk-1 + fk-2. Use induction to prove that for every n ? 0, fn ? 2n-1 . Base case should start at f0 and f1. For the inductive case of fk+1 , you’ll need to use the inductive hypothesis for both k and k ? 1.

The Fibonacci numbers are defined recursively as follows: fo = 0, fi = 1 and fn fn-l fn-2 for all n > 2. Prove that for all non-negative integers n: fnfn+2= (fn+1)2 - (-1)"
Fibonacci num Fn are defined as follow. F0 is 1, F1 is 1, and Fi+2 = Fi + Fi+1, where i = 0, 1, 2, . . . . In other words, each number is the sum of the previous two numbers. Write a recursive function definition in C++ that has one parameter n of type int and that returns the n-th Fibonacci number. You can call this function inside the main function to print the Fibonacci numbers. Sample Input...

(a) Characterize the set of integers n for which fn is even and prove your answer using induction (b) Please do b as well. The Fibonacci numbers are defined as follows: fi -1, f21, and fn+2 nfn+1 whenever n 21. (a) Characterize the set of integers n for which fn is even and prove your answer using induction.
