Halfway Between 85 and 727

When you ask "What number is halfway between 85 and 727?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=85 and Y=727.

Halfway Between Line

To find the number halfway between 85 and 727, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 727 into our formula, we get:

(85 + 727)/2 = 406

Thus, the number halfway between 85 and 727 is 406.

To check that our answer is correct, we subtract 85 from 406 and subtract 406 from 727 and compare the two numbers:

406 - 85 = 321
727 - 406 = 321

As you can see, the halfway number is 321 higher than 85 and 321 lower than 727. Therefore, our halfway between answer of 406 above is correct.
