Halfway Between 9 and 85

When you ask "What number is halfway between 9 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=9 and Y=85.

Halfway Between Line

To find the number halfway between 9 and 85, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 85 into our formula, we get:

(9 + 85)/2 = 47

Thus, the number halfway between 9 and 85 is 47.

To check that our answer is correct, we subtract 9 from 47 and subtract 47 from 85 and compare the two numbers:

47 - 9 = 38
85 - 47 = 38

As you can see, the halfway number is 38 higher than 9 and 38 lower than 85. Therefore, our halfway between answer of 47 above is correct.
