Halfway Between 4 and 85

When you ask "What number is halfway between 4 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=4 and Y=85.

Halfway Between Line

To find the number halfway between 4 and 85, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 85 into our formula, we get:

(4 + 85)/2 = 44.5

Thus, the number halfway between 4 and 85 is 44.5.

To check that our answer is correct, we subtract 4 from 44.5 and subtract 44.5 from 85 and compare the two numbers:

44.5 - 4 = 40.5
85 - 44.5 = 40.5

As you can see, the halfway number is 40.5 higher than 4 and 40.5 lower than 85. Therefore, our halfway between answer of 44.5 above is correct.
