Halfway Between 15 and 529

When you ask "What number is halfway between 15 and 529?" 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=529.

Halfway Between Line

To find the number halfway between 15 and 529, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 529 into our formula, we get:

(15 + 529)/2 = 272

Thus, the number halfway between 15 and 529 is 272.

To check that our answer is correct, we subtract 15 from 272 and subtract 272 from 529 and compare the two numbers:

272 - 15 = 257
529 - 272 = 257

As you can see, the halfway number is 257 higher than 15 and 257 lower than 529. Therefore, our halfway between answer of 272 above is correct.
