Halfway Between 80 and 721

When you ask "What number is halfway between 80 and 721?" 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=721.

Halfway Between Line

To find the number halfway between 80 and 721, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 721 into our formula, we get:

(80 + 721)/2 = 400.5

Thus, the number halfway between 80 and 721 is 400.5.

To check that our answer is correct, we subtract 80 from 400.5 and subtract 400.5 from 721 and compare the two numbers:

400.5 - 80 = 320.5
721 - 400.5 = 320.5

As you can see, the halfway number is 320.5 higher than 80 and 320.5 lower than 721. Therefore, our halfway between answer of 400.5 above is correct.
