Halfway Between 8 and 89

When you ask "What number is halfway between 8 and 89?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=8 and Y=89.

Halfway Between Line

To find the number halfway between 8 and 89, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 8 and 89 into our formula, we get:

(8 + 89)/2 = 48.5

Thus, the number halfway between 8 and 89 is 48.5.

To check that our answer is correct, we subtract 8 from 48.5 and subtract 48.5 from 89 and compare the two numbers:

48.5 - 8 = 40.5
89 - 48.5 = 40.5

As you can see, the halfway number is 40.5 higher than 8 and 40.5 lower than 89. Therefore, our halfway between answer of 48.5 above is correct.
