Halfway Between 9 and 667

When you ask "What number is halfway between 9 and 667?" 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=667.

Halfway Between Line

To find the number halfway between 9 and 667, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 667 into our formula, we get:

(9 + 667)/2 = 338

Thus, the number halfway between 9 and 667 is 338.

To check that our answer is correct, we subtract 9 from 338 and subtract 338 from 667 and compare the two numbers:

338 - 9 = 329
667 - 338 = 329

As you can see, the halfway number is 329 higher than 9 and 329 lower than 667. Therefore, our halfway between answer of 338 above is correct.
