Halfway Between 15 and 345

When you ask "What number is halfway between 15 and 345?" 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=345.

Halfway Between Line

To find the number halfway between 15 and 345, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 345 into our formula, we get:

(15 + 345)/2 = 180

Thus, the number halfway between 15 and 345 is 180.

To check that our answer is correct, we subtract 15 from 180 and subtract 180 from 345 and compare the two numbers:

180 - 15 = 165
345 - 180 = 165

As you can see, the halfway number is 165 higher than 15 and 165 lower than 345. Therefore, our halfway between answer of 180 above is correct.
