Hello,
I'm just starting out my GMAT study journey and have come across a question for which I think I'm being very dense. I just don't understand the question, nor do I understand the answer. Maybe I'm trying to make more out of it than I should. However,
The question is:
If x is an integer and y = 3x + 2, which of the following CANNOT be a divisor of y?
A. 4
B. 5
C. 6
D. 7
E. 8
The answer is 6, because 3x can be divided by 3, but 3x+2 can't, therefore, 6 can't.
What am I missing - because to me, for the same reason that 3x+2 can't be divided by 6, it can't be divided by 5 either (for a small iteration from x=1 to 4, for instance).
