Halfway Between 78 and 316

When you ask "What number is halfway between 78 and 316?" 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=316.

Halfway Between Line

To find the number halfway between 78 and 316, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 316 into our formula, we get:

(78 + 316)/2 = 197

Thus, the number halfway between 78 and 316 is 197.

To check that our answer is correct, we subtract 78 from 197 and subtract 197 from 316 and compare the two numbers:

197 - 78 = 119
316 - 197 = 119

As you can see, the halfway number is 119 higher than 78 and 119 lower than 316. Therefore, our halfway between answer of 197 above is correct.
