WebProof by strong induction Step 1. Demonstrate the base case: This is where you verify that P (k_0) P (k0) is true. In most cases, k_0=1. k0 = 1. Step 2. Prove the inductive step: This is where you assume that all of P (k_0) P (k0), P (k_0+1), P (k_0+2), \ldots, P (k) P (k0 +1),P (k0 +2),…,P (k) are true (our inductive hypothesis). WebProof.

WebFeb 2, 2024 · First proof (by Binet’s formula) Let the roots of x^2 - x - 1 = 0 be a and b. The explicit expressions for a and b are a = (1+sqrt [5])/2, b = (1-sqrt [5])/2. In particular, a + b = 1, a - b = sqrt (5), and a*b = -1. Also a^2 = a + 1, b^2 = b + 1. Then the Binet Formula for the k-th Fibonacci number is F (k) = (a^k-b^k)/ (a-b).
