Halfway Between 8 and 85

When you ask "What number is halfway between 8 and 85?" 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=85.

Halfway Between Line

To find the number halfway between 8 and 85, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 8 and 85 into our formula, we get:

(8 + 85)/2 = 46.5

Thus, the number halfway between 8 and 85 is 46.5.

To check that our answer is correct, we subtract 8 from 46.5 and subtract 46.5 from 85 and compare the two numbers:

46.5 - 8 = 38.5
85 - 46.5 = 38.5

As you can see, the halfway number is 38.5 higher than 8 and 38.5 lower than 85. Therefore, our halfway between answer of 46.5 above is correct.
