Fill in a number in the brackets below to make the median of this set of data 29? 10.50.18.15.25.34.48

thirty-three
The solution is as follows
Step 1: from small to large: 10,15,18,25,34,48,50
Step 2: locate the median 29 between 25 and 34
Step 3: because there are 8 data, the median 29 is the average of 25 and (), that is, 25 + () = 29x2, so () = 33
