Question: 309

1. If n is 3 times an even number, then which of the following could be n?

A. 14
B. 15
C. 16
D. 17
E. 18

Correct Answer: E

Explanation:

E Since n is equal to 3 times an even number, you can eliminate any answer choice that is not a multiple of 3 (A, C, and D). Answer choice (B): 15 = 3 × 5; 5 is an odd number, so this answer choice is out. Answer choice (E): 18 = 3 × 6; 6 is an even number.
