Halfway Between 15 and 519

When you ask "What number is halfway between 15 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=15 and Y=519.

Halfway Between Line

To find the number halfway between 15 and 519, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 519 into our formula, we get:

(15 + 519)/2 = 267

Thus, the number halfway between 15 and 519 is 267.

To check that our answer is correct, we subtract 15 from 267 and subtract 267 from 519 and compare the two numbers:

267 - 15 = 252
519 - 267 = 252

As you can see, the halfway number is 252 higher than 15 and 252 lower than 519. Therefore, our halfway between answer of 267 above is correct.
