WebFibonacci Sequence: F (0) = 1, F (1) = 2, F (n) = F (n − 1) + F (n − 2) for n ≥ 2 (a) Use strong induction to show that F (n) ≤ 2^n for all n ≥ 0. (b) The answer for (a) shows that F (n) is O (2^n). If we could also show that F (n) is Ω (2^n), that would mean that F (n) is Θ (2^n), and our order of growth would be F (n). WebProbably the easiest way, as mm-aops suggests, is to use the general relationship [m,n] = (m,n)mn. In this case, that reduces the problem to showing that (n,n+1) = 1, which is …
