Halfway Between 45 and 721

When you ask "What number is halfway between 45 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=45 and Y=721.

Halfway Between Line

To find the number halfway between 45 and 721, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 721 into our formula, we get:

(45 + 721)/2 = 383

Thus, the number halfway between 45 and 721 is 383.

To check that our answer is correct, we subtract 45 from 383 and subtract 383 from 721 and compare the two numbers:

383 - 45 = 338
721 - 383 = 338

As you can see, the halfway number is 338 higher than 45 and 338 lower than 721. Therefore, our halfway between answer of 383 above is correct.
