Halfway Between 80 and 855

When you ask "What number is halfway between 80 and 855?" 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=855.

Halfway Between Line

To find the number halfway between 80 and 855, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 855 into our formula, we get:

(80 + 855)/2 = 467.5

Thus, the number halfway between 80 and 855 is 467.5.

To check that our answer is correct, we subtract 80 from 467.5 and subtract 467.5 from 855 and compare the two numbers:

467.5 - 80 = 387.5
855 - 467.5 = 387.5

As you can see, the halfway number is 387.5 higher than 80 and 387.5 lower than 855. Therefore, our halfway between answer of 467.5 above is correct.
