Halfway Between 100 and 180

When you ask "What number is halfway between 100 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=100 and Y=180.

Halfway Between Line

To find the number halfway between 100 and 180, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 180 into our formula, we get:

(100 + 180)/2 = 140

Thus, the number halfway between 100 and 180 is 140.

To check that our answer is correct, we subtract 100 from 140 and subtract 140 from 180 and compare the two numbers:

140 - 100 = 40
180 - 140 = 40

As you can see, the halfway number is 40 higher than 100 and 40 lower than 180. Therefore, our halfway between answer of 140 above is correct.
