Halfway Between 15 and 655

When you ask "What number is halfway between 15 and 655?" 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=655.

Halfway Between Line

To find the number halfway between 15 and 655, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 655 into our formula, we get:

(15 + 655)/2 = 335

Thus, the number halfway between 15 and 655 is 335.

To check that our answer is correct, we subtract 15 from 335 and subtract 335 from 655 and compare the two numbers:

335 - 15 = 320
655 - 335 = 320

As you can see, the halfway number is 320 higher than 15 and 320 lower than 655. Therefore, our halfway between answer of 335 above is correct.
