Halfway Between 13 and 329

When you ask "What number is halfway between 13 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=13 and Y=329.

Halfway Between Line

To find the number halfway between 13 and 329, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 329 into our formula, we get:

(13 + 329)/2 = 171

Thus, the number halfway between 13 and 329 is 171.

To check that our answer is correct, we subtract 13 from 171 and subtract 171 from 329 and compare the two numbers:

171 - 13 = 158
329 - 171 = 158

As you can see, the halfway number is 158 higher than 13 and 158 lower than 329. Therefore, our halfway between answer of 171 above is correct.
