Halfway Between 15 and 641

When you ask "What number is halfway between 15 and 641?" 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=641.

Halfway Between Line

To find the number halfway between 15 and 641, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 641 into our formula, we get:

(15 + 641)/2 = 328

Thus, the number halfway between 15 and 641 is 328.

To check that our answer is correct, we subtract 15 from 328 and subtract 328 from 641 and compare the two numbers:

328 - 15 = 313
641 - 328 = 313

As you can see, the halfway number is 313 higher than 15 and 313 lower than 641. Therefore, our halfway between answer of 328 above is correct.
