(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. Since 9j(10k 1) we know that 10k 1 ...

WebbProof by Induction Suppose that you want to prove that some property P(n) holds of all natural numbers. To do so: Prove that P(0) is true. – This is called the basis or the base case. Prove that for all n ∈ ℕ, that if P(n) is true, then P(n + 1) is true as well. – This is called the inductive step. – P(n) is called the inductive hypothesis. Webb3 / 7 Directionality in Induction In the inductive step of a proof, you need to prove this statement: If P(k) is true, then P(k+1) is true. Typically, in an inductive proof, you'd start off by assuming that P(k) was true, then would proceed to show that P(k+1) must also be true. In practice, it can be easy to inadvertently get this backwards.
Webba specific integer k. (In other words, the step in which we prove (a).) Inductive step: The step in a proof by induction in which we prove that, for all n ≥ k, P(n) ⇒ P(n+1). (I.e., the step in which we prove (b).) Inductive hypothesis: Within the inductive step, we assume P(n). This assumption is called the inductive hypothesis.
WebbOverview: Proof by induction is done in two steps.
