Halfway Between 1 and 81

When you ask "What number is halfway between 1 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=1 and Y=81.

Halfway Between Line

To find the number halfway between 1 and 81, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 81 into our formula, we get:

(1 + 81)/2 = 41

Thus, the number halfway between 1 and 81 is 41.

To check that our answer is correct, we subtract 1 from 41 and subtract 41 from 81 and compare the two numbers:

41 - 1 = 40
81 - 41 = 40

As you can see, the halfway number is 40 higher than 1 and 40 lower than 81. Therefore, our halfway between answer of 41 above is correct.
