Halfway Between 1 and 17

When you ask "What number is halfway between 1 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=1 and Y=17.

Halfway Between Line

To find the number halfway between 1 and 17, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 17 into our formula, we get:

(1 + 17)/2 = 9

Thus, the number halfway between 1 and 17 is 9.

To check that our answer is correct, we subtract 1 from 9 and subtract 9 from 17 and compare the two numbers:

9 - 1 = 8
17 - 9 = 8

As you can see, the halfway number is 8 higher than 1 and 8 lower than 17. Therefore, our halfway between answer of 9 above is correct.
