Halfway Between 78 and 388

When you ask "What number is halfway between 78 and 388?" 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=388.

Halfway Between Line

To find the number halfway between 78 and 388, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 388 into our formula, we get:

(78 + 388)/2 = 233

Thus, the number halfway between 78 and 388 is 233.

To check that our answer is correct, we subtract 78 from 233 and subtract 233 from 388 and compare the two numbers:

233 - 78 = 155
388 - 233 = 155

As you can see, the halfway number is 155 higher than 78 and 155 lower than 388. Therefore, our halfway between answer of 233 above is correct.
