Halfway Between 5 and 78

When you ask "What number is halfway between 5 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=5 and Y=78.

Halfway Between Line

To find the number halfway between 5 and 78, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 78 into our formula, we get:

(5 + 78)/2 = 41.5

Thus, the number halfway between 5 and 78 is 41.5.

To check that our answer is correct, we subtract 5 from 41.5 and subtract 41.5 from 78 and compare the two numbers:

41.5 - 5 = 36.5
78 - 41.5 = 36.5

As you can see, the halfway number is 36.5 higher than 5 and 36.5 lower than 78. Therefore, our halfway between answer of 41.5 above is correct.
