After arranging the numbers in ascending order, x being the median will take values between 11-14. Since your question is asking only one value of x, i think you should find the mean of 11 and 14. I think it will be 12.5

10 , 18 , 4 , 15 , 3 , 21 , x
First arrange the values in the sorted order
position of median will be (7+1)/2 = 4
3, 4,10, x, 15,21
so the possibile value will be between 10 and 15

I think the median is all the numbers added together, then divided by how many numbers there are. Try it, but it's been a loooong time since my math days.

x can be 11,12,13,14

3,4,10,15,18,21
so we must put x after10
3,4,10, 11,12,13,14,15,18,21
so x=11or12or13or14
