Halfway Between 25 and 78

When you ask "What number is halfway between 25 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=25 and Y=78.

Halfway Between Line

To find the number halfway between 25 and 78, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 25 and 78 into our formula, we get:

(25 + 78)/2 = 51.5

Thus, the number halfway between 25 and 78 is 51.5.

To check that our answer is correct, we subtract 25 from 51.5 and subtract 51.5 from 78 and compare the two numbers:

51.5 - 25 = 26.5
78 - 51.5 = 26.5

As you can see, the halfway number is 26.5 higher than 25 and 26.5 lower than 78. Therefore, our halfway between answer of 51.5 above is correct.
