Halfway Between 40 and 81

When you ask "What number is halfway between 40 and 81?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=40 and Y=81.

Halfway Between Line

To find the number halfway between 40 and 81, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 81 into our formula, we get:

(40 + 81)/2 = 60.5

Thus, the number halfway between 40 and 81 is 60.5.

To check that our answer is correct, we subtract 40 from 60.5 and subtract 60.5 from 81 and compare the two numbers:

60.5 - 40 = 20.5
81 - 60.5 = 20.5

As you can see, the halfway number is 20.5 higher than 40 and 20.5 lower than 81. Therefore, our halfway between answer of 60.5 above is correct.
