... P (n + 1) for all n. We prove (b) by contradiction. Suppose P (n) is not true for all n ∈ N. Set E = {n | P (n) is false}. Then E = ∅ and is a subset of the natural numbers. By the well-ordering property there is a least such n which we label n0 . Since P (1) is true, n0 > 1. By construction, P (n0 ...
