Halfway Between 85 and 709

When you ask "What number is halfway between 85 and 709?" 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=709.

Halfway Between Line

To find the number halfway between 85 and 709, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 709 into our formula, we get:

(85 + 709)/2 = 397

Thus, the number halfway between 85 and 709 is 397.

To check that our answer is correct, we subtract 85 from 397 and subtract 397 from 709 and compare the two numbers:

397 - 85 = 312
709 - 397 = 312

As you can see, the halfway number is 312 higher than 85 and 312 lower than 709. Therefore, our halfway between answer of 397 above is correct.
