Halfway Between 78 and 385

When you ask "What number is halfway between 78 and 385?" 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=385.

Halfway Between Line

To find the number halfway between 78 and 385, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 385 into our formula, we get:

(78 + 385)/2 = 231.5

Thus, the number halfway between 78 and 385 is 231.5.

To check that our answer is correct, we subtract 78 from 231.5 and subtract 231.5 from 385 and compare the two numbers:

231.5 - 78 = 153.5
385 - 231.5 = 153.5

As you can see, the halfway number is 153.5 higher than 78 and 153.5 lower than 385. Therefore, our halfway between answer of 231.5 above is correct.
