Halfway Between 1 and 721

When you ask "What number is halfway between 1 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=1 and Y=721.

Halfway Between Line

To find the number halfway between 1 and 721, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 721 into our formula, we get:

(1 + 721)/2 = 361

Thus, the number halfway between 1 and 721 is 361.

To check that our answer is correct, we subtract 1 from 361 and subtract 361 from 721 and compare the two numbers:

361 - 1 = 360
721 - 361 = 360

As you can see, the halfway number is 360 higher than 1 and 360 lower than 721. Therefore, our halfway between answer of 361 above is correct.
