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.

(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...

Fibonacci sequence: Cauchy-Binet formula Let (Fn)n be the Fibo- nacci sequence defined recursively by F1 = F2 = 1 and Fn = Fn−1 + Fn−2In this way it all reduces to computing a high power of a 2 × 2 matrix. How can you compute an arbitrary power of a matrix and can you come up with the Cauchy-Binet formula from here?
