WebTo prove divisibility by induction show that the statement is true for the first number in the series (base case). Then use the inductive hypothesis and assume that the statement is true for some arbitrary number, n. Using the inductive hypothesis, prove that the statement is true for the next number in the series, n+1. Webat which point we can use the inductive hypothesis. Explicitly, 52k+2 1 = 52 52k 1 = 52(52k 1 + 1) 1 = 52(3‘+ 1) 1 = 75‘+ 24: Since 75‘ is a multiple of 3 and so is 24, we see that 52k+2 1 …

Webpart of the induction hypothesis. You need to distinguish between the Claim and the Induction Hypothesis. The Claim is the statement you want to prove (i.e., ∀n ≥ 0,S n), whereas the Induction Hypothesis is an assumption you make (i.e., ∀0 ≤ k ≤ n,S n), which you use to prove the next statement (i.e., S n+1).
