Halfway Between 17 and 505

When you ask "What number is halfway between 17 and 505?" 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=505.

Halfway Between Line

To find the number halfway between 17 and 505, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 505 into our formula, we get:

(17 + 505)/2 = 261

Thus, the number halfway between 17 and 505 is 261.

To check that our answer is correct, we subtract 17 from 261 and subtract 261 from 505 and compare the two numbers:

261 - 17 = 244
505 - 261 = 244

As you can see, the halfway number is 244 higher than 17 and 244 lower than 505. Therefore, our halfway between answer of 261 above is correct.
