Proving P0(n) by regular induction is the same as proving P(n) by strong induction. 14 An example using strong induction Theorem: Any item costing n > 7 kopecks can be bought using only 3-kopeck and 5-kopeck coins. Proof: Using strong induction. Let P(n) be the state-ment that n kopecks can be paid using 3-kopeck and 5-kopeck coins, for n ...

Webmethod is called “strong” induction. A proof by strong induction looks like this: Proof: We will show P(n) is true for all n, using induction on n. Base: We need to show that P(1) is true. Induction: Suppose that P(1) up through P(k) are all true, for some integer k. We need to show that P(k +1) is true. 2 WebStrong is on the rise this week.
