WebLet’s look at a few examples of proof by induction. In these examples, we will structure our proofs explicitly to label the base case, inductive hypothesis, and inductive step. This is … Webstrong induction, which allowed us to use a broader induction hypothesis. This example could also have been done with regular mathematical induction, but it would have taken …
WebJun 30, 2024 · Theorem 5.2.1. Every way of unstacking n blocks gives a score of n(n − 1) / 2 points. There are a couple technical points to notice in the proof: The template for a strong induction proof mirrors the one for ordinary induction. As with ordinary induction, we have some freedom to adjust indices. WebWe noted in the previous exercise that we needed to modify our induction hypothesis so that the hypothesis is true at k and at k-1.We will fix this problem by supposing, for all integers between our largest base case (we saw from the last exercise that this is n = 3) and some integer k, that: (k + 1) + k + (k − 1) = 3 k (k+1) + k + (k-1) = 3k (k + 1) + k + (k − 1) = 3 k
