Halfway Between 78 and 512

When you ask "What number is halfway between 78 and 512?" 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=512.

Halfway Between Line

To find the number halfway between 78 and 512, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 512 into our formula, we get:

(78 + 512)/2 = 295

Thus, the number halfway between 78 and 512 is 295.

To check that our answer is correct, we subtract 78 from 295 and subtract 295 from 512 and compare the two numbers:

295 - 78 = 217
512 - 295 = 217

As you can see, the halfway number is 217 higher than 78 and 217 lower than 512. Therefore, our halfway between answer of 295 above is correct.
