Halfway Between 20 and 100

When you ask "What number is halfway between 20 and 100?" 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=100.

Halfway Between Line

To find the number halfway between 20 and 100, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 100 into our formula, we get:

(20 + 100)/2 = 60

Thus, the number halfway between 20 and 100 is 60.

To check that our answer is correct, we subtract 20 from 60 and subtract 60 from 100 and compare the two numbers:

60 - 20 = 40
100 - 60 = 40

As you can see, the halfway number is 40 higher than 20 and 40 lower than 100. Therefore, our halfway between answer of 60 above is correct.
