Halfway Between 45 and 729

When you ask "What number is halfway between 45 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=45 and Y=729.

Halfway Between Line

To find the number halfway between 45 and 729, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 729 into our formula, we get:

(45 + 729)/2 = 387

Thus, the number halfway between 45 and 729 is 387.

To check that our answer is correct, we subtract 45 from 387 and subtract 387 from 729 and compare the two numbers:

387 - 45 = 342
729 - 387 = 342

As you can see, the halfway number is 342 higher than 45 and 342 lower than 729. Therefore, our halfway between answer of 387 above is correct.
