Halfway Between 80 and 891

When you ask "What number is halfway between 80 and 891?" 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=891.

Halfway Between Line

To find the number halfway between 80 and 891, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 891 into our formula, we get:

(80 + 891)/2 = 485.5

Thus, the number halfway between 80 and 891 is 485.5.

To check that our answer is correct, we subtract 80 from 485.5 and subtract 485.5 from 891 and compare the two numbers:

485.5 - 80 = 405.5
891 - 485.5 = 405.5

As you can see, the halfway number is 405.5 higher than 80 and 405.5 lower than 891. Therefore, our halfway between answer of 485.5 above is correct.
