Halfway Between 78 and 432

When you ask "What number is halfway between 78 and 432?" 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=432.

Halfway Between Line

To find the number halfway between 78 and 432, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 432 into our formula, we get:

(78 + 432)/2 = 255

Thus, the number halfway between 78 and 432 is 255.

To check that our answer is correct, we subtract 78 from 255 and subtract 255 from 432 and compare the two numbers:

255 - 78 = 177
432 - 255 = 177

As you can see, the halfway number is 177 higher than 78 and 177 lower than 432. Therefore, our halfway between answer of 255 above is correct.
