Halfway Between 15 and 559

When you ask "What number is halfway between 15 and 559?" 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=559.

Halfway Between Line

To find the number halfway between 15 and 559, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 559 into our formula, we get:

(15 + 559)/2 = 287

Thus, the number halfway between 15 and 559 is 287.

To check that our answer is correct, we subtract 15 from 287 and subtract 287 from 559 and compare the two numbers:

287 - 15 = 272
559 - 287 = 272

As you can see, the halfway number is 272 higher than 15 and 272 lower than 559. Therefore, our halfway between answer of 287 above is correct.
