Halfway Between 1 and 9

When you ask "What number is halfway between 1 and 9?" 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=9.

Halfway Between Line

To find the number halfway between 1 and 9, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 9 into our formula, we get:

(1 + 9)/2 = 5

Thus, the number halfway between 1 and 9 is 5.

To check that our answer is correct, we subtract 1 from 5 and subtract 5 from 9 and compare the two numbers:

5 - 1 = 4
9 - 5 = 4

As you can see, the halfway number is 4 higher than 1 and 4 lower than 9. Therefore, our halfway between answer of 5 above is correct.
