Halfway Between 78 and 310

When you ask "What number is halfway between 78 and 310?" 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=310.

Halfway Between Line

To find the number halfway between 78 and 310, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 310 into our formula, we get:

(78 + 310)/2 = 194

Thus, the number halfway between 78 and 310 is 194.

To check that our answer is correct, we subtract 78 from 194 and subtract 194 from 310 and compare the two numbers:

194 - 78 = 116
310 - 194 = 116

As you can see, the halfway number is 116 higher than 78 and 116 lower than 310. Therefore, our halfway between answer of 194 above is correct.
