Halfway Between 72 and 721

When you ask "What number is halfway between 72 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=72 and Y=721.

Halfway Between Line

To find the number halfway between 72 and 721, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 72 and 721 into our formula, we get:

(72 + 721)/2 = 396.5

Thus, the number halfway between 72 and 721 is 396.5.

To check that our answer is correct, we subtract 72 from 396.5 and subtract 396.5 from 721 and compare the two numbers:

396.5 - 72 = 324.5
721 - 396.5 = 324.5

As you can see, the halfway number is 324.5 higher than 72 and 324.5 lower than 721. Therefore, our halfway between answer of 396.5 above is correct.
