Halfway Between 66 and 564

When you ask "What number is halfway between 66 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=66 and Y=564.

Halfway Between Line

To find the number halfway between 66 and 564, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 564 into our formula, we get:

(66 + 564)/2 = 315

Thus, the number halfway between 66 and 564 is 315.

To check that our answer is correct, we subtract 66 from 315 and subtract 315 from 564 and compare the two numbers:

315 - 66 = 249
564 - 315 = 249

As you can see, the halfway number is 249 higher than 66 and 249 lower than 564. Therefore, our halfway between answer of 315 above is correct.
