Halfway Between 13 and 729

When you ask "What number is halfway between 13 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=13 and Y=729.

Halfway Between Line

To find the number halfway between 13 and 729, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 729 into our formula, we get:

(13 + 729)/2 = 371

Thus, the number halfway between 13 and 729 is 371.

To check that our answer is correct, we subtract 13 from 371 and subtract 371 from 729 and compare the two numbers:

371 - 13 = 358
729 - 371 = 358

As you can see, the halfway number is 358 higher than 13 and 358 lower than 729. Therefore, our halfway between answer of 371 above is correct.
