Halfway Between 78 and 381

When you ask "What number is halfway between 78 and 381?" 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=381.

Halfway Between Line

To find the number halfway between 78 and 381, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 381 into our formula, we get:

(78 + 381)/2 = 229.5

Thus, the number halfway between 78 and 381 is 229.5.

To check that our answer is correct, we subtract 78 from 229.5 and subtract 229.5 from 381 and compare the two numbers:

229.5 - 78 = 151.5
381 - 229.5 = 151.5

As you can see, the halfway number is 151.5 higher than 78 and 151.5 lower than 381. Therefore, our halfway between answer of 229.5 above is correct.
