WebAn 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 8. Basis: P(8) is clearly true since 8 = 3+5. Inductive step: Assume P(8);:::;P(n) is true. We WebThis means that strong induction allows us to assume n predicates are true, rather than just 1, when proving P(n+1) is true. For example, in ordinary induction, we must prove P(3) is true assuming P(2) is true. But in strong induction, we must prove P(3) is true assuming P(1) and P(2) are both true.
