If the median of the data: 6, 7, x − 2, x, 17, 20, written in ascending order, is 16. Then x =
Terms are 6, 7, x - 2, x, 17, 20
No of terms = 6
We know that, if even no of terms or observations are given, then the median of data is mean of the values of 
term and 
term. Where n is no of terms.
In this case, n = 6
i.e. median of above data is mean of 3rd and 4th term
⇒ median 
⇒ 16 = x - 1 [As median is 16]
⇒ x = 17
16
