Halfway Between 15 and 584

When you ask "What number is halfway between 15 and 584?" 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=584.

Halfway Between Line

To find the number halfway between 15 and 584, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 584 into our formula, we get:

(15 + 584)/2 = 299.5

Thus, the number halfway between 15 and 584 is 299.5.

To check that our answer is correct, we subtract 15 from 299.5 and subtract 299.5 from 584 and compare the two numbers:

299.5 - 15 = 284.5
584 - 299.5 = 284.5

As you can see, the halfway number is 284.5 higher than 15 and 284.5 lower than 584. Therefore, our halfway between answer of 299.5 above is correct.
