Halfway Between 13 and 17

When you ask "What number is halfway between 13 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=13 and Y=17.

Halfway Between Line

To find the number halfway between 13 and 17, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 17 into our formula, we get:

(13 + 17)/2 = 15

Thus, the number halfway between 13 and 17 is 15.

To check that our answer is correct, we subtract 13 from 15 and subtract 15 from 17 and compare the two numbers:

15 - 13 = 2
17 - 15 = 2

As you can see, the halfway number is 2 higher than 13 and 2 lower than 17. Therefore, our halfway between answer of 15 above is correct.
