Halfway Between 13 and 81

When you ask "What number is halfway between 13 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=13 and Y=81.

Halfway Between Line

To find the number halfway between 13 and 81, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 81 into our formula, we get:

(13 + 81)/2 = 47

Thus, the number halfway between 13 and 81 is 47.

To check that our answer is correct, we subtract 13 from 47 and subtract 47 from 81 and compare the two numbers:

47 - 13 = 34
81 - 47 = 34

As you can see, the halfway number is 34 higher than 13 and 34 lower than 81. Therefore, our halfway between answer of 47 above is correct.
