( 1 + k) s + 1 = ( 1 + k) ( 1 + k) s = ( 1 + k) s + k ( 1 + k) s ≥ ( 1 + k s) + k = 1 + k ( s + 1), where the inequality above holds because of the induction step and because 1 + k > 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
