It is 15, the number halfway between the two middle numbers.
11.5
(14 + 42) / 2 = 28
List the numbers in numerical order. You are looking for the middle number. In this case it will be the number halfway between the 4th and 5th number. Add the 4th and 5th numbers and divide them by 2, or find the number exactly halfway between the 4th and 5th numbers. So if your 4th number was 12 and your 5th number was 16, then the value halfway between them or the number that is half of the value when you add the two together is 14. That is the median.
