(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.

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!
MATLAB 1. The Fibonacci sequence is defined by the recurrence relation Fn = Fn-1+Fn-2 where Fo = 0 and F1 = 1. Hence F2 = 1, F3 = 2, F4 = 3, etc. In this problem you will use three different methods to compute the n-th element of the sequence. Then, you will compare the time complexity of these methods. (a) Write a recursive function called fibRec with the following declaration line begin code function nElem = fibrec (n) end...
(5) Fibonacci sequences in groups. The Fibonacci numbers F, are defined recursively by Fo = 0, Fi-1, and Fn Fn-1 + Fn-2 for n > 2. The definition of this sequence only depends on a binary operation. Since every group comes with a binary operation, we can define Fibonacc type sequences in any group.
