Halfway Between 85 and 873

When you ask "What number is halfway between 85 and 873?" 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=873.

Halfway Between Line

To find the number halfway between 85 and 873, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 873 into our formula, we get:

(85 + 873)/2 = 479

Thus, the number halfway between 85 and 873 is 479.

To check that our answer is correct, we subtract 85 from 479 and subtract 479 from 873 and compare the two numbers:

479 - 85 = 394
873 - 479 = 394

As you can see, the halfway number is 394 higher than 85 and 394 lower than 873. Therefore, our halfway between answer of 479 above is correct.
