hmmm, is it safe to assume the set is already sorted in ascending order? Are we allowed to assume on the gmat? if not the answer is (E)..nothing tells us that w is the smallest or largest number

it doesnot matter whether the set is sorted or not, if the difference of any two elements of the set is more than two, the range is more then 2.
