Halfway Between 89 and 180

When you ask "What number is halfway between 89 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=89 and Y=180.

Halfway Between Line

To find the number halfway between 89 and 180, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 180 into our formula, we get:

(89 + 180)/2 = 134.5

Thus, the number halfway between 89 and 180 is 134.5.

To check that our answer is correct, we subtract 89 from 134.5 and subtract 134.5 from 180 and compare the two numbers:

134.5 - 89 = 45.5
180 - 134.5 = 45.5

As you can see, the halfway number is 45.5 higher than 89 and 45.5 lower than 180. Therefore, our halfway between answer of 134.5 above is correct.
