Halfway Between 78 and 564

When you ask "What number is halfway between 78 and 564?" 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=564.

Halfway Between Line

To find the number halfway between 78 and 564, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 564 into our formula, we get:

(78 + 564)/2 = 321

Thus, the number halfway between 78 and 564 is 321.

To check that our answer is correct, we subtract 78 from 321 and subtract 321 from 564 and compare the two numbers:

321 - 78 = 243
564 - 321 = 243

As you can see, the halfway number is 243 higher than 78 and 243 lower than 564. Therefore, our halfway between answer of 321 above is correct.
