Halfway Between 88 and 891

When you ask "What number is halfway between 88 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=88 and Y=891.

Halfway Between Line

To find the number halfway between 88 and 891, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 88 and 891 into our formula, we get:

(88 + 891)/2 = 489.5

Thus, the number halfway between 88 and 891 is 489.5.

To check that our answer is correct, we subtract 88 from 489.5 and subtract 489.5 from 891 and compare the two numbers:

489.5 - 88 = 401.5
891 - 489.5 = 401.5

As you can see, the halfway number is 401.5 higher than 88 and 401.5 lower than 891. Therefore, our halfway between answer of 489.5 above is correct.
