Halfway Between 85 and 677

When you ask "What number is halfway between 85 and 677?" 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=677.

Halfway Between Line

To find the number halfway between 85 and 677, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 677 into our formula, we get:

(85 + 677)/2 = 381

Thus, the number halfway between 85 and 677 is 381.

To check that our answer is correct, we subtract 85 from 381 and subtract 381 from 677 and compare the two numbers:

381 - 85 = 296
677 - 381 = 296

As you can see, the halfway number is 296 higher than 85 and 296 lower than 677. Therefore, our halfway between answer of 381 above is correct.
