In math, the median of a set of numbers is the number that lays directly in the middle.
To find this out we must lay the number from either increasing to decreasing or decreasing to increasing:
100, 98, 94, 92, 90, 88, 84, 82, 78, 72,
Now, because we have an even number of numbers in our set, that means there is no exact middle number.
So to solve, you take the two numbers closest to the middle (90 & 88), add them up and divide by 2.
90 + 88 = 178
178 / 2 = 89
So the median is 89.
Hope this helps!
