Question

What is the midpoint of -4 and 20?

Answer 1

Answer: 8

Step-by-step explanation: 4+20=24

24/2= 12

-4+12 = 8

Answer 2

In one dimensions (i.e. with standard numbers and not points with more coordinates) the midpoint is the same as the average.

The average of two numbers is their sum divided by two.

So, we have -4+20=16. Divide this by two to get 8.
