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. We prove that P(1) P ( 1) is true (or ... WebbThe well-ordering property accounts for most of the facts you find "natural" about the natural numbers. In fact, the principle of induction and the well-ordering property are equivalent. This explains why induction proofs are so common when dealing with the natural numbers — it's baked right into the structure of the natural numbers themselves.

Example 4 Consider the sequence deﬁned by b(0) = 0 b(1) = 1 b(n) = b(jn 2 k) +b(ln 2 m), for n ≥ 2. If you look at the ﬁrst ﬁve or six terms of this sequence, it is not hard to come up with a very simple guess: b(n) = n. We can prove it by strong induction.
