Why is the number 1 odd?

All natural numbers are testable except for one. A number must be able to be tested in this way before being called an odd number. 1 cannot be tested in this way, and therefore it cannot be called an odd number. The un-testability of the number of one makes it impossible to judge whether it is odd or even.

## How do you prove that 2k 1 is odd?

Proof: Let x be an arbitrary odd number. By definition, an odd number is an integer that can be written in the form 2k + 1, for some integer k. This means we can write x = 2k + 1, where k is some integer. So x2 = (2k + 1)2 = 4k2 + 4k + 1 = 2(2k2 + 2k) + 1.
