Compute the first 10 Fibonacci numbers. Typically, proofs involving the Fibonacci numbers require a proof by complete induction. For example: Claim. For any , . … WebbTo prove P ( n) with induction is a two-step procedure. Base case: Show that P (0) is true. Inductive step: Show that P ( k) is true if P ( i) is true for all i < k. The statement ”P ( i) is true for all i < k ” is often called the induction hypothesis.

Webb7 juli 2024 · To make use of the inductive hypothesis, we need to apply the recurrence relation of Fibonacci numbers.
