Five numbers in increasing order are 2, 5, $x, 10$, and $y$. The median of the numbers is 7 and the mean (average) is 8 . The value of $y$ is
(A) 16
(B) 14
(C) 15
(D) 18
(E) 12
When a set of five numbers is listed in ascending order, the median of the set is the middle number in the list, or the third number in this case.

Since the median is 7 and $x$ is the middle number, then $x=7$.

Therefore, the list is $2,5,7,10, y$.

Since the mean of the five numbers is 8 , then the sum of the numbers is $5 \times 8=40$.

Therefore, $2+5+7+10+y=40$ or $24+y=40$ or $y=16$.

ANSWER: (A)
