Halfway Between 17 and 521

When you ask "What number is halfway between 17 and 521?" 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=521.

Halfway Between Line

To find the number halfway between 17 and 521, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 521 into our formula, we get:

(17 + 521)/2 = 269

Thus, the number halfway between 17 and 521 is 269.

To check that our answer is correct, we subtract 17 from 269 and subtract 269 from 521 and compare the two numbers:

269 - 17 = 252
521 - 269 = 252

As you can see, the halfway number is 252 higher than 17 and 252 lower than 521. Therefore, our halfway between answer of 269 above is correct.
