Halfway Between 78 and 130

When you ask "What number is halfway between 78 and 130?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=78 and Y=130.

Halfway Between Line

To find the number halfway between 78 and 130, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 130 into our formula, we get:

(78 + 130)/2 = 104

Thus, the number halfway between 78 and 130 is 104.

To check that our answer is correct, we subtract 78 from 104 and subtract 104 from 130 and compare the two numbers:

104 - 78 = 26
130 - 104 = 26

As you can see, the halfway number is 26 higher than 78 and 26 lower than 130. Therefore, our halfway between answer of 104 above is correct.
