sum of n consecutive integers = 10n
n is odd.
let first =a, then last = a+(n-1)
2a + n =21..
b) a+n-1=34 -> a+n=35. thus a = -14. Sufficient.
a)range=14
a+n-1 -a = 14. n =15. 2a+15=21. a = 3. Sufficient.
IMO D

Hi [email protected]!

Would you mind checking the information for the original source - this question is a definite NO NO when it comes to the world of GMAT - the two statements both give definitive solutions, but those solutions DO NOT match!

Lets look at the statements together: If the highest number is 34, and the range is 14, the smallest number would be 20. But if the terms are 20 through 34, the average CANNOT be 10. Something is wrong with this problem because the GMAT will never have the statements disagree!

Let us know when you have verified the problem so we can help
