Halfway Between 85 and 871

When you ask "What number is halfway between 85 and 871?" 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=871.

Halfway Between Line

To find the number halfway between 85 and 871, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 871 into our formula, we get:

(85 + 871)/2 = 478

Thus, the number halfway between 85 and 871 is 478.

To check that our answer is correct, we subtract 85 from 478 and subtract 478 from 871 and compare the two numbers:

478 - 85 = 393
871 - 478 = 393

As you can see, the halfway number is 393 higher than 85 and 393 lower than 871. Therefore, our halfway between answer of 478 above is correct.
