Halfway Between 17 and 618

When you ask "What number is halfway between 17 and 618?" 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=618.

Halfway Between Line

To find the number halfway between 17 and 618, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 618 into our formula, we get:

(17 + 618)/2 = 317.5

Thus, the number halfway between 17 and 618 is 317.5.

To check that our answer is correct, we subtract 17 from 317.5 and subtract 317.5 from 618 and compare the two numbers:

317.5 - 17 = 300.5
618 - 317.5 = 300.5

As you can see, the halfway number is 300.5 higher than 17 and 300.5 lower than 618. Therefore, our halfway between answer of 317.5 above is correct.
