If S N is a subset of the natural numbers such that (i)0 2S, and (ii) whenever k 2S, then k + 1 2S, then S = N:
WebProof by contradiction can be applied to a much broader class of statements than proof by contraposition, which only works for implications. But there are proofs of implications by contradiction that cannot be directly rephrased into proofs by contraposition. Proposition: If x is a multiple of 6 then x is a multiple of 2. Proof.
