Halfway Between 80 and 677

When you ask "What number is halfway between 80 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=80 and Y=677.

Halfway Between Line

To find the number halfway between 80 and 677, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 677 into our formula, we get:

(80 + 677)/2 = 378.5

Thus, the number halfway between 80 and 677 is 378.5.

To check that our answer is correct, we subtract 80 from 378.5 and subtract 378.5 from 677 and compare the two numbers:

378.5 - 80 = 298.5
677 - 378.5 = 298.5

As you can see, the halfway number is 298.5 higher than 80 and 298.5 lower than 677. Therefore, our halfway between answer of 378.5 above is correct.
