Halfway Between 15 and 329

When you ask "What number is halfway between 15 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=15 and Y=329.

Halfway Between Line

To find the number halfway between 15 and 329, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 329 into our formula, we get:

(15 + 329)/2 = 172

Thus, the number halfway between 15 and 329 is 172.

To check that our answer is correct, we subtract 15 from 172 and subtract 172 from 329 and compare the two numbers:

172 - 15 = 157
329 - 172 = 157

As you can see, the halfway number is 157 higher than 15 and 157 lower than 329. Therefore, our halfway between answer of 172 above is correct.
