Halfway Between 8 and 78

When you ask "What number is halfway between 8 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=8 and Y=78.

Halfway Between Line

To find the number halfway between 8 and 78, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 8 and 78 into our formula, we get:

(8 + 78)/2 = 43

Thus, the number halfway between 8 and 78 is 43.

To check that our answer is correct, we subtract 8 from 43 and subtract 43 from 78 and compare the two numbers:

43 - 8 = 35
78 - 43 = 35

As you can see, the halfway number is 35 higher than 8 and 35 lower than 78. Therefore, our halfway between answer of 43 above is correct.
