What is the value of n in the list above?

(1) k < n
(2) The median of the numbers in the list is 10.

1. k<n doesnt help us to find the value of n - Insufficient
2.) median is 10 , 10 can be either k or n - insufficient

Combining
One of k and n is 10 and it is the middle value
since we have 12 and 17 already more than 10; the other number should be less than 10

since k is less than n k is a number which is less than 10 and n is 10

Correct
