Halfway Between 4 and 78

When you ask "What number is halfway between 4 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=4 and Y=78.

Halfway Between Line

To find the number halfway between 4 and 78, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 78 into our formula, we get:

(4 + 78)/2 = 41

Thus, the number halfway between 4 and 78 is 41.

To check that our answer is correct, we subtract 4 from 41 and subtract 41 from 78 and compare the two numbers:

41 - 4 = 37
78 - 41 = 37

As you can see, the halfway number is 37 higher than 4 and 37 lower than 78. Therefore, our halfway between answer of 41 above is correct.
