If I remember correctly, more is the middle. So you first line up the numbers from least to greatest-
25,20,20,20,22
Then you count equally from each side to get to the number in the middle.
The answer would be 20
For future references, if there are two numbers in the middle, you and them together, and then divide that number by two.
Hope this helps!
