WebbStrong induction is a type of proof closely related to simple induction. As in simple induction, we have a statement P(n) P ( n) about the whole number n n, and we want to prove that P(n) P ( n) is true for every value of n n. To prove this using strong induction, we do the following: The base case. WebbStrong Induction Examples - Strong induction Margaret M.
