median of a set of numbers is the middle number when the set is arranged in ascending(descending) order if the number of elements in the set is odd
If the number elements in thr set is even then it is the average of two middle numbers.
{ n, k, 2, 8, 12 } is a odd set

a) if the median is 7 then either k is 7 or n is seven ( insufficient )
b) k > n k = 1 n = 0 or k = 10 n = 1 (insufficeint)

combine both
if median is 7 and k > n then k must be 7
