Halfway Between 2 and 78

When you ask "What number is halfway between 2 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=2 and Y=78.

Halfway Between Line

To find the number halfway between 2 and 78, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 2 and 78 into our formula, we get:

(2 + 78)/2 = 40

Thus, the number halfway between 2 and 78 is 40.

To check that our answer is correct, we subtract 2 from 40 and subtract 40 from 78 and compare the two numbers:

40 - 2 = 38
78 - 40 = 38

As you can see, the halfway number is 38 higher than 2 and 38 lower than 78. Therefore, our halfway between answer of 40 above is correct.
