## Homework Statement

Let n be any odd integer. Prove that 1 is the only "common" divisor of the integers n and n+2.

## The Attempt at a Solution

I don't think I understand the question.

The few notes I have state d| (n+2 )- n

This resembles n+2 ##\equiv## n mod d , but I don't see the connection.

The congruency means that n+2 and n share the same remainder.

Any help?
