Halfway Between 15 and 393

When you ask "What number is halfway between 15 and 393?" 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=393.

Halfway Between Line

To find the number halfway between 15 and 393, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 393 into our formula, we get:

(15 + 393)/2 = 204

Thus, the number halfway between 15 and 393 is 204.

To check that our answer is correct, we subtract 15 from 204 and subtract 204 from 393 and compare the two numbers:

204 - 15 = 189
393 - 204 = 189

As you can see, the halfway number is 189 higher than 15 and 189 lower than 393. Therefore, our halfway between answer of 204 above is correct.
