If m and n are integers, is m odd? 1) n + m is odd : If m+n is odd m can be odd or m can be even because we don't know the value of n so this statement is insufficient 2) n + m = n^2 + 5 : We know that n and n^2 have the same parity ; that is if n is even n^2 is even and so on .... then m = n^2-n +...
