Halfway Between 17 and 563

When you ask "What number is halfway between 17 and 563?" 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=563.

Halfway Between Line

To find the number halfway between 17 and 563, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 563 into our formula, we get:

(17 + 563)/2 = 290

Thus, the number halfway between 17 and 563 is 290.

To check that our answer is correct, we subtract 17 from 290 and subtract 290 from 563 and compare the two numbers:

290 - 17 = 273
563 - 290 = 273

As you can see, the halfway number is 273 higher than 17 and 273 lower than 563. Therefore, our halfway between answer of 290 above is correct.
