Halfway Between 63 and 78

When you ask "What number is halfway between 63 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=63 and Y=78.

Halfway Between Line

To find the number halfway between 63 and 78, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 63 and 78 into our formula, we get:

(63 + 78)/2 = 70.5

Thus, the number halfway between 63 and 78 is 70.5.

To check that our answer is correct, we subtract 63 from 70.5 and subtract 70.5 from 78 and compare the two numbers:

70.5 - 63 = 7.5
78 - 70.5 = 7.5

As you can see, the halfway number is 7.5 higher than 63 and 7.5 lower than 78. Therefore, our halfway between answer of 70.5 above is correct.
