R n 1 induction
WebJan 21, 2015 · Proof by induction on n: Step 1: prove that the equation is valid when n = 1. When n = 1, we have (2 (1) - 1) = 12, so the statement holds for n = 1. Step 2: Assume that the equation is true for n, and prove that the equation is true for n + 1. Assume: 1 + 3 + 5 + ... + (2n - 1) = n2. Prove: 1 + 3 + 5 +...+ (2 (n + 1) - 1) = (n + 1)2. 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
