Question

If 3k is an even number integer which of the following cannot be an integer ?

A : k
B : k - 1
C : k/2
D : 3k

Answer 1

c and a

because 3k has to add up the an even number so k by it self can not be an even number, and k/2 would still be an odd number because an off number divided by a even number still makes it odd
