Halfway Between 48 and 81

When you ask "What number is halfway between 48 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=48 and Y=81.

Halfway Between Line

To find the number halfway between 48 and 81, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 48 and 81 into our formula, we get:

(48 + 81)/2 = 64.5

Thus, the number halfway between 48 and 81 is 64.5.

To check that our answer is correct, we subtract 48 from 64.5 and subtract 64.5 from 81 and compare the two numbers:

64.5 - 48 = 16.5
81 - 64.5 = 16.5

As you can see, the halfway number is 16.5 higher than 48 and 16.5 lower than 81. Therefore, our halfway between answer of 64.5 above is correct.
