Halfway Between 17 and 517

When you ask "What number is halfway between 17 and 517?" 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=517.

Halfway Between Line

To find the number halfway between 17 and 517, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 517 into our formula, we get:

(17 + 517)/2 = 267

Thus, the number halfway between 17 and 517 is 267.

To check that our answer is correct, we subtract 17 from 267 and subtract 267 from 517 and compare the two numbers:

267 - 17 = 250
517 - 267 = 250

As you can see, the halfway number is 250 higher than 17 and 250 lower than 517. Therefore, our halfway between answer of 267 above is correct.
