Halfway Between 55 and 729

When you ask "What number is halfway between 55 and 729?" 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=729.

Halfway Between Line

To find the number halfway between 55 and 729, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 729 into our formula, we get:

(55 + 729)/2 = 392

Thus, the number halfway between 55 and 729 is 392.

To check that our answer is correct, we subtract 55 from 392 and subtract 392 from 729 and compare the two numbers:

392 - 55 = 337
729 - 392 = 337

As you can see, the halfway number is 337 higher than 55 and 337 lower than 729. Therefore, our halfway between answer of 392 above is correct.
