Inductive proofs are similar to direct proofs in which every step must be justified, but they utilize a special three step process and … WebbYou then multiply each term by 2 as all even numbers are multiples of 2. Therefore the consecutive even terms are 2 (n), 2 (n + 1), 2 (n + 2) which can be simplified to 2n, 2n + 2, 2n + 4 etc. Expressing consecutive odd numbers is a little bit more complicated than expressing consecutive even numbers as odd numbers are not part of a multiple.
