Best Answer

When arranged in ascending or descending order, the median is the value which lies half-way along the series.

Where there is an even number of values in the set then the median is the mean of the middle two values.

As there are 7 values in the given set, and one is missing, then the full set comprises 8 values.

2,7,8,14,15,20,29.

The middle value is 14 so we need another value, v such that, ½(14 + v) = 13.

This solves as v = 12.

The full set now is,2,7,8,12,14,15,20,29.
