Answer:

The median is 21

Step-by-step explanation:

Since you have 12 numbers in order, that's an even number, once you put them in numerical order and start crossing them off on both sides, you'll have 18 and 24 left, add them together and divide them by 2 and you'll have your median 21.

28 and 12 are in the middle, so add them up you get 40
Divide by 2 = 20

Hope this helps :D
