Halfway Between 1 and 517

When you ask "What number is halfway between 1 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=1 and Y=517.

Halfway Between Line

To find the number halfway between 1 and 517, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 517 into our formula, we get:

(1 + 517)/2 = 259

Thus, the number halfway between 1 and 517 is 259.

To check that our answer is correct, we subtract 1 from 259 and subtract 259 from 517 and compare the two numbers:

259 - 1 = 258
517 - 259 = 258

As you can see, the halfway number is 258 higher than 1 and 258 lower than 517. Therefore, our halfway between answer of 259 above is correct.
