Halfway Between 17 and 539

When you ask "What number is halfway between 17 and 539?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=17 and Y=539.

Halfway Between Line

To find the number halfway between 17 and 539, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 539 into our formula, we get:

(17 + 539)/2 = 278

Thus, the number halfway between 17 and 539 is 278.

To check that our answer is correct, we subtract 17 from 278 and subtract 278 from 539 and compare the two numbers:

278 - 17 = 261
539 - 278 = 261

As you can see, the halfway number is 261 higher than 17 and 261 lower than 539. Therefore, our halfway between answer of 278 above is correct.
