Halfway Between 9 and 329

When you ask "What number is halfway between 9 and 329?" 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=329.

Halfway Between Line

To find the number halfway between 9 and 329, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 329 into our formula, we get:

(9 + 329)/2 = 169

Thus, the number halfway between 9 and 329 is 169.

To check that our answer is correct, we subtract 9 from 169 and subtract 169 from 329 and compare the two numbers:

169 - 9 = 160
329 - 169 = 160

As you can see, the halfway number is 160 higher than 9 and 160 lower than 329. Therefore, our halfway between answer of 169 above is correct.
