Halfway Between 55 and 726

When you ask "What number is halfway between 55 and 726?" 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=726.

Halfway Between Line

To find the number halfway between 55 and 726, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 726 into our formula, we get:

(55 + 726)/2 = 390.5

Thus, the number halfway between 55 and 726 is 390.5.

To check that our answer is correct, we subtract 55 from 390.5 and subtract 390.5 from 726 and compare the two numbers:

390.5 - 55 = 335.5
726 - 390.5 = 335.5

As you can see, the halfway number is 335.5 higher than 55 and 335.5 lower than 726. Therefore, our halfway between answer of 390.5 above is correct.
