Answer: 16 (answer D)
Explanation:
reorder numerically
6, 8, 12, 16, 24
14 times 2 = 28
12 is the middle number
28-12= 16
if you add 16 to the sequence then the median will be 14. the median is the middle number. however, there are two middle numbers.
6, 8, 12, 16, 16, 24
what you would do is add the two middle numbers then divide by 2.
check
12+16= 28
28/2 = 14
