Halfway Between 77 and 180

When you ask "What number is halfway between 77 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=77 and Y=180.

Halfway Between Line

To find the number halfway between 77 and 180, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 77 and 180 into our formula, we get:

(77 + 180)/2 = 128.5

Thus, the number halfway between 77 and 180 is 128.5.

To check that our answer is correct, we subtract 77 from 128.5 and subtract 128.5 from 180 and compare the two numbers:

128.5 - 77 = 51.5
180 - 128.5 = 51.5

As you can see, the halfway number is 51.5 higher than 77 and 51.5 lower than 180. Therefore, our halfway between answer of 128.5 above is correct.
