Halfway Between 90 and 564

When you ask "What number is halfway between 90 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=90 and Y=564.

Halfway Between Line

To find the number halfway between 90 and 564, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 564 into our formula, we get:

(90 + 564)/2 = 327

Thus, the number halfway between 90 and 564 is 327.

To check that our answer is correct, we subtract 90 from 327 and subtract 327 from 564 and compare the two numbers:

327 - 90 = 237
564 - 327 = 237

As you can see, the halfway number is 237 higher than 90 and 237 lower than 564. Therefore, our halfway between answer of 327 above is correct.
