Given:
sum of the first three terms is 39
sum of the last four terms is 179
if the first term is 10, then the median of the A.P is:

10, 13, 16, 19, 22, 25, 28, 31, 34, 37, 40, 43, 46, 49

10 + 13 + 16 = 39
40 + 43 + 46 + 49 = 178

A.P or arithmetic progression is a sequence of numbers that have a common difference. In the above set, the common difference is 3.

10, 13, 16, 19, 22, 25, 28, 31, 34, 37, 40, 43, 46, 49

median = 28+31 = 59/2 = 29.50
