Strong inductive proof for this inequality using the Fibonacci sequence.

WebInduction Hypothesis: Assume that F n > 2 n holds true for all n ∈ { 8,..., k }, where k ≥ 8. It remains to prove the inequality true for n = k + 1. Observe that: F k + 1 = F k + F k − 1 > 2 k + 2 ( k − 1) by the induction hypothesis ≥ 2 k + 2 ( 8 − 1) since k ≥ 8 = 2 k + 14 > 2 k + 2 = 2 ( k + 1) as desired. This completes the induction.
