Halfway Between 17 and 519

When you ask "What number is halfway between 17 and 519?" 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=519.

Halfway Between Line

To find the number halfway between 17 and 519, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 519 into our formula, we get:

(17 + 519)/2 = 268

Thus, the number halfway between 17 and 519 is 268.

To check that our answer is correct, we subtract 17 from 268 and subtract 268 from 519 and compare the two numbers:

268 - 17 = 251
519 - 268 = 251

As you can see, the halfway number is 251 higher than 17 and 251 lower than 519. Therefore, our halfway between answer of 268 above is correct.
