Answer:

  False

Step-by-step explanation:

 counterexample: 3 + 7 = 10 . . . . not divisible by 4

The statement is FALSE.

__

An odd number can be represented by ...

  2n+1 . . . . where n is any integer

Then a different odd number can be represented by ...

  2m +1 . . . . where m is any integer

The sum of these numbers will be ...

  (2n +1) +(2m +1) = 2n +2m +2 = 2(n +m +1)

This will be divisible by 2 for any integers m and n, but will only be divisible by 4 if exactly one of the integers m and n is odd.
