Halfway Between 90 and 180

When you ask "What number is halfway between 90 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=90 and Y=180.

Halfway Between Line

To find the number halfway between 90 and 180, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 180 into our formula, we get:

(90 + 180)/2 = 135

Thus, the number halfway between 90 and 180 is 135.

To check that our answer is correct, we subtract 90 from 135 and subtract 135 from 180 and compare the two numbers:

135 - 90 = 45
180 - 135 = 45

As you can see, the halfway number is 45 higher than 90 and 45 lower than 180. Therefore, our halfway between answer of 135 above is correct.
