Halfway Between 5 and 81

When you ask "What number is halfway between 5 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=5 and Y=81.

Halfway Between Line

To find the number halfway between 5 and 81, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 81 into our formula, we get:

(5 + 81)/2 = 43

Thus, the number halfway between 5 and 81 is 43.

To check that our answer is correct, we subtract 5 from 43 and subtract 43 from 81 and compare the two numbers:

43 - 5 = 38
81 - 43 = 38

As you can see, the halfway number is 38 higher than 5 and 38 lower than 81. Therefore, our halfway between answer of 43 above is correct.
