| Type | Parity and evenness proofs |
| Difficulty | Easy -1.2 This is a straightforward proof requiring only basic algebraic representation of odd numbers (2n+1, 2n+3) and simple expansion to show the product is odd. It's a standard textbook exercise testing understanding of parity definitions with minimal steps and no conceptual challenges beyond the basic setup. |
| Spec | 1.01a Proof: structure of mathematical proof and logical steps |
16. Use algebra to prove that the product of any two consecutive odd numbers is an odd number.
