Halfway Between 15 and 603

When you ask "What number is halfway between 15 and 603?" 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=603.

Halfway Between Line

To find the number halfway between 15 and 603, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 603 into our formula, we get:

(15 + 603)/2 = 309

Thus, the number halfway between 15 and 603 is 309.

To check that our answer is correct, we subtract 15 from 309 and subtract 309 from 603 and compare the two numbers:

309 - 15 = 294
603 - 309 = 294

As you can see, the halfway number is 294 higher than 15 and 294 lower than 603. Therefore, our halfway between answer of 309 above is correct.
