Halfway Between 80 and 728

When you ask "What number is halfway between 80 and 728?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=80 and Y=728.

Halfway Between Line

To find the number halfway between 80 and 728, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 728 into our formula, we get:

(80 + 728)/2 = 404

Thus, the number halfway between 80 and 728 is 404.

To check that our answer is correct, we subtract 80 from 404 and subtract 404 from 728 and compare the two numbers:

404 - 80 = 324
728 - 404 = 324

As you can see, the halfway number is 324 higher than 80 and 324 lower than 728. Therefore, our halfway between answer of 404 above is correct.
