Halfway Between 9 and 626

When you ask "What number is halfway between 9 and 626?" 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=626.

Halfway Between Line

To find the number halfway between 9 and 626, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 626 into our formula, we get:

(9 + 626)/2 = 317.5

Thus, the number halfway between 9 and 626 is 317.5.

To check that our answer is correct, we subtract 9 from 317.5 and subtract 317.5 from 626 and compare the two numbers:

317.5 - 9 = 308.5
626 - 317.5 = 308.5

As you can see, the halfway number is 308.5 higher than 9 and 308.5 lower than 626. Therefore, our halfway between answer of 317.5 above is correct.
