Halfway Between 65 and 78

When you ask "What number is halfway between 65 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=65 and Y=78.

Halfway Between Line

To find the number halfway between 65 and 78, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 65 and 78 into our formula, we get:

(65 + 78)/2 = 71.5

Thus, the number halfway between 65 and 78 is 71.5.

To check that our answer is correct, we subtract 65 from 71.5 and subtract 71.5 from 78 and compare the two numbers:

71.5 - 65 = 6.5
78 - 71.5 = 6.5

As you can see, the halfway number is 6.5 higher than 65 and 6.5 lower than 78. Therefore, our halfway between answer of 71.5 above is correct.
