x is the sum of y consecutive integers. w is the sum of z consecutive integers. If y = 2z, and y and z are both positive integers, then each of the following could be true EXCEPT
x = w
x > w
x/y is an integer
w/z is an integer
x/z is an integer
OA C [spoiler]Although I learned new concept today about consecutive integers and understand why the answer is indeed correct, I can't refute the other options when I choose variables for each integers in this form: a + a+1+a+2....
for example, to prove a is wrong, the OE simply picked any number of integer, but why when I pick variables it does not work ?[/spoiler]
