Halfway Between 78 and 387

When you ask "What number is halfway between 78 and 387?" 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=387.

Halfway Between Line

To find the number halfway between 78 and 387, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 387 into our formula, we get:

(78 + 387)/2 = 232.5

Thus, the number halfway between 78 and 387 is 232.5.

To check that our answer is correct, we subtract 78 from 232.5 and subtract 232.5 from 387 and compare the two numbers:

232.5 - 78 = 154.5
387 - 232.5 = 154.5

As you can see, the halfway number is 154.5 higher than 78 and 154.5 lower than 387. Therefore, our halfway between answer of 232.5 above is correct.
