WebOct 26, 2015 · I have a problem similar to: Let S defined recursively by (1) 5 ∈ S and (2) if s ∈ S and t ∈ S, then st ∈ S. Let. A = {5^i i ∈ Z+}. prove that S ⊆ A by structural induction. I've only done mathematical induction and I'm not sure I understand the differences. WebOutline for Mathematical Induction To show that a propositional function P(n) is true for all integers n ≥ a, follow these steps: Base Step: Verify that P(a) is true. Inductive Step: Show that if P(k) is true for some integer k ≥ a, then P(k + 1) is also true. Assume P(n) is true for an arbitrary integer, k with k ≥ a .
