Halfway Between 9 and 17

When you ask "What number is halfway between 9 and 17?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=9 and Y=17.

Halfway Between Line

To find the number halfway between 9 and 17, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 17 into our formula, we get:

(9 + 17)/2 = 13

Thus, the number halfway between 9 and 17 is 13.

To check that our answer is correct, we subtract 9 from 13 and subtract 13 from 17 and compare the two numbers:

13 - 9 = 4
17 - 13 = 4

As you can see, the halfway number is 4 higher than 9 and 4 lower than 17. Therefore, our halfway between answer of 13 above is correct.
