Halfway Between 15 and 649

When you ask "What number is halfway between 15 and 649?" 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=649.

Halfway Between Line

To find the number halfway between 15 and 649, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 649 into our formula, we get:

(15 + 649)/2 = 332

Thus, the number halfway between 15 and 649 is 332.

To check that our answer is correct, we subtract 15 from 332 and subtract 332 from 649 and compare the two numbers:

332 - 15 = 317
649 - 332 = 317

As you can see, the halfway number is 317 higher than 15 and 317 lower than 649. Therefore, our halfway between answer of 332 above is correct.
