Halfway Between 85 and 711

When you ask "What number is halfway between 85 and 711?" 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=711.

Halfway Between Line

To find the number halfway between 85 and 711, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 711 into our formula, we get:

(85 + 711)/2 = 398

Thus, the number halfway between 85 and 711 is 398.

To check that our answer is correct, we subtract 85 from 398 and subtract 398 from 711 and compare the two numbers:

398 - 85 = 313
711 - 398 = 313

As you can see, the halfway number is 313 higher than 85 and 313 lower than 711. Therefore, our halfway between answer of 398 above is correct.
