WebNov 15, 2011 · For induction, you have to prove the base case. Then you assume your induction hypothesis, which in this case is 2 n >= n 2. After that you want to prove that it is true for n + 1, i.e. that 2 n+1 >= (n+1) 2. You will use the induction hypothesis in the proof (the assumption that 2 n >= n 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 Webonly works when n 7 (and our inductive step just does not work when n is 5 or 6). All is not lost!
