Halfway Between 70 and 728

When you ask "What number is halfway between 70 and 728?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=70 and Y=728.

Halfway Between Line

To find the number halfway between 70 and 728, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 70 and 728 into our formula, we get:

(70 + 728)/2 = 399

Thus, the number halfway between 70 and 728 is 399.

To check that our answer is correct, we subtract 70 from 399 and subtract 399 from 728 and compare the two numbers:

399 - 70 = 329
728 - 399 = 329

As you can see, the halfway number is 329 higher than 70 and 329 lower than 728. Therefore, our halfway between answer of 399 above is correct.
