Halfway Between 10 and 85

When you ask "What number is halfway between 10 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=10 and Y=85.

Halfway Between Line

To find the number halfway between 10 and 85, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 10 and 85 into our formula, we get:

(10 + 85)/2 = 47.5

Thus, the number halfway between 10 and 85 is 47.5.

To check that our answer is correct, we subtract 10 from 47.5 and subtract 47.5 from 85 and compare the two numbers:

47.5 - 10 = 37.5
85 - 47.5 = 37.5

As you can see, the halfway number is 37.5 higher than 10 and 37.5 lower than 85. Therefore, our halfway between answer of 47.5 above is correct.
