Halfway Between 20 and 180

When you ask "What number is halfway between 20 and 180?" 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=180.

Halfway Between Line

To find the number halfway between 20 and 180, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 180 into our formula, we get:

(20 + 180)/2 = 100

Thus, the number halfway between 20 and 180 is 100.

To check that our answer is correct, we subtract 20 from 100 and subtract 100 from 180 and compare the two numbers:

100 - 20 = 80
180 - 100 = 80

As you can see, the halfway number is 80 higher than 20 and 80 lower than 180. Therefore, our halfway between answer of 100 above is correct.
