# If Q is an odd number and the median of Q consecutive integers is 120, what is the largest of these integers? GMAT Explanation

If Q is an odd number and the median of Q consecutive integers is 120, what is the largest of these integers?

(A) (Q – 1)/2 + 120

(B) Q/2 + 119

(C) Q/2 + 120

(D) (Q + 119)/2

(E) (Q + 120)/2

To me this screams: pick a value for Q. Just make sure that you follow any rules outlined in the question. Always take your time to get things straight. That doesn’t mean sit and stare. Or obsessively re-read things. That means find the pace and level of detail that allows you to comprehend the question. Pause. Think. Digest.

So the median is 120, Q is an odd number, and there are Q consecutive integers. We’re looking for: *the largest of these integers.*

If 120 is the middle number (median) let’s just add one above and once below: 119 120 121

So, since Q represents the number of numbers, Q is 3. That value follows the rule: Q is odd.

## Plug back into the answer choices and look out for shortcuts (choices that clearly won’t match 121)

Now what? Now we do what we always do picking values and plug back into the answer choices. We need to sub in 3 for Q and output 121 (the largest of these integers).

You can rule out some of these without doing much since you can see fractions that clearly won’t work (B, C, E).

Then work out A and D.

D you can also eyeball. It’s way too small to equal 121.

It has to be A.

**Correct Answer:** A
