Halfway Between 2 and 17

When you ask "What number is halfway between 2 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=2 and Y=17.

Halfway Between Line

To find the number halfway between 2 and 17, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 2 and 17 into our formula, we get:

(2 + 17)/2 = 9.5

Thus, the number halfway between 2 and 17 is 9.5.

To check that our answer is correct, we subtract 2 from 9.5 and subtract 9.5 from 17 and compare the two numbers:

9.5 - 2 = 7.5
17 - 9.5 = 7.5

As you can see, the halfway number is 7.5 higher than 2 and 7.5 lower than 17. Therefore, our halfway between answer of 9.5 above is correct.
