Halfway Between 80 and 857

When you ask "What number is halfway between 80 and 857?" 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=857.

Halfway Between Line

To find the number halfway between 80 and 857, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 857 into our formula, we get:

(80 + 857)/2 = 468.5

Thus, the number halfway between 80 and 857 is 468.5.

To check that our answer is correct, we subtract 80 from 468.5 and subtract 468.5 from 857 and compare the two numbers:

468.5 - 80 = 388.5
857 - 468.5 = 388.5

As you can see, the halfway number is 388.5 higher than 80 and 388.5 lower than 857. Therefore, our halfway between answer of 468.5 above is correct.
