2n + 3
2n (n + 3)
Answer explanation
We are told that n is an odd integer. So choose an odd integer for n, say, 1 and substitute it into each answer-choice. Now, n ^ 3 becomes 1 ^ 3 = 1 which is not an even Integer. So eliminate (A). Next, n / 4 -> 1/4 Is not an even integer-eliminate (B). Next, 2n + 3 = 2 1 + 3 = 5 is not an even integer-eliminate (C). Next, 2n(n+3)=2^ 1(1 + 3) = 4 is even and hence the answer is possibly (D).

If p and q are positive integers, how many integers are larger than pq and smaller than p (q + 2)?
3
p + 2
p - 2
2p - 1
Answer explanation
Let p = 1 and q = 2 Then pq = 2 and p(q + 2) = 4 This scenario has one integer, 3, greater than pq and less than p(q + 2) Now, we plug p = 1 and q = 2 into the answer-choices we find one that has the value 1. Look at choice (D): 2p - 1 = (2)(1) - 1 = 1 Thus, the answer is (D).

Speed bumps are being placed at 25 foot intervals along a road 1015 feet long. If the first speed bump is placed at one end of the road, how many speed bumps are needed?
39
40
41
52
Answer explanation
Since the road is 1015 feet long and the speed bumps are 25 feet apart, there are 1015/25 = 40.6 or 40 full sections in the road. If we ignore the first speed bump and associate the speed bump at the end of each section with that section, then there are 40 speed bumps (one for each of the fifty full sections). Counting the first speed bump gives a total of 41 speed bumps. The answer is (C).
