Halfway Between 55 and 721

When you ask "What number is halfway between 55 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=55 and Y=721.

Halfway Between Line

To find the number halfway between 55 and 721, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 721 into our formula, we get:

(55 + 721)/2 = 388

Thus, the number halfway between 55 and 721 is 388.

To check that our answer is correct, we subtract 55 from 388 and subtract 388 from 721 and compare the two numbers:

388 - 55 = 333
721 - 388 = 333

As you can see, the halfway number is 333 higher than 55 and 333 lower than 721. Therefore, our halfway between answer of 388 above is correct.
