Question

5 positive integers are arranged in ascending order, as follows:
5, 7, 10, 11, X
The mean and the median are equal.
Find X.

Answer 1

The answer is: 10.

Explanation: The numbers are in order by the median/lowest to highest so in that case X wouldn't be 7 because the X would have been next to the 7 not on the other side of the 10.
