Halfway Between 15 and 566

When you ask "What number is halfway between 15 and 566?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=15 and Y=566.

Halfway Between Line

To find the number halfway between 15 and 566, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 566 into our formula, we get:

(15 + 566)/2 = 290.5

Thus, the number halfway between 15 and 566 is 290.5.

To check that our answer is correct, we subtract 15 from 290.5 and subtract 290.5 from 566 and compare the two numbers:

290.5 - 15 = 275.5
566 - 290.5 = 275.5

As you can see, the halfway number is 275.5 higher than 15 and 275.5 lower than 566. Therefore, our halfway between answer of 290.5 above is correct.
