4/16, 5/20, 6/24, 7/28, 8/32...
I think the answer should be divisible because you can’t really divide 1 without getting the same # your dividing by.
Firstly arrange data from smaller to greater data point:
4 5 6 9 10 11 12 13 15 16
Secondly find the middle value: In our case the number of data is even, so to get the middle value we have to find the mean (average) between 10 & 11, that is 10.5. So the rank of the Median is10.5
