Halfway Between 78 and 116

When you ask "What number is halfway between 78 and 116?" 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=116.

Halfway Between Line

To find the number halfway between 78 and 116, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 116 into our formula, we get:

(78 + 116)/2 = 97

Thus, the number halfway between 78 and 116 is 97.

To check that our answer is correct, we subtract 78 from 97 and subtract 97 from 116 and compare the two numbers:

97 - 78 = 19
116 - 97 = 19

As you can see, the halfway number is 19 higher than 78 and 19 lower than 116. Therefore, our halfway between answer of 97 above is correct.
