Halfway Between 23 and 78

When you ask "What number is halfway between 23 and 78?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=23 and Y=78.

Halfway Between Line

To find the number halfway between 23 and 78, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 23 and 78 into our formula, we get:

(23 + 78)/2 = 50.5

Thus, the number halfway between 23 and 78 is 50.5.

To check that our answer is correct, we subtract 23 from 50.5 and subtract 50.5 from 78 and compare the two numbers:

50.5 - 23 = 27.5
78 - 50.5 = 27.5

As you can see, the halfway number is 27.5 higher than 23 and 27.5 lower than 78. Therefore, our halfway between answer of 50.5 above is correct.
