"WebTheorem: The sum of the first n powers of two is 2n – 1. Proof: By induction.Let P(n) be “the sum of the first n powers of two is 2n – 1.” We will show P(n) is true for all n ∈ ℕ. For our base case, we need to show P(0) is true, meaning the sum of the first zero powers of two is 20 – 1. Since the sum of the first zero powers of two is 0 = 20 – 1, we see " - Strong induction proof of n n-1 /2

WebTo prove an statement using strong induction , in base case we have to show the statement is true for smallest value of n. Since n = 0 is the smallest value for which a n is defined so in base case we have shown that the statement is true for n = 0, 1. 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.
