Halfway Between 20 and 108

When you ask "What number is halfway between 20 and 108?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=20 and Y=108.

Halfway Between Line

To find the number halfway between 20 and 108, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 108 into our formula, we get:

(20 + 108)/2 = 64

Thus, the number halfway between 20 and 108 is 64.

To check that our answer is correct, we subtract 20 from 64 and subtract 64 from 108 and compare the two numbers:

64 - 20 = 44
108 - 64 = 44

As you can see, the halfway number is 44 higher than 20 and 44 lower than 108. Therefore, our halfway between answer of 64 above is correct.
