what would be a counterexample of this converse statement:

Question

If a and b are even number, then a+b is a consecutive odd number.

Answer 1

contra example

a and b are 4 and 6
then a+b is 10 which is not odd.

Answer 2

Is this suppose to be something like..

(a-4 b-6)

a+b= ?

If so then it equals 10
cause 4+6=10
