WebbThe ﬁrst four are fairly simple proofs by induction. The last required realizing that we could easily prove that P(n) ⇒ P(n + 3). We could prove the statement by doing three separate inductions, or we could use the Principle of Strong Induction. Principle of Strong Induction Let k be an integer and let P(n) be a statement for each integer n ... Webbcases of the recurrence relation.) These ideas are illustrated in the next example. 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. WebbAnother Mathematical Induction Example Proposition 9j(10n 1) for all integers n 0. Proof. (By induction on n.) When n = 0 we nd 10n 1 = 100 1 = 0 and since 9j0 we see the statement holds for n = 0. Now suppose the statement holds for all values of n up to some integer k; we need to show it holds for k + 1.
