Halfway Between 15 and 699

When you ask "What number is halfway between 15 and 699?" 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=699.

Halfway Between Line

To find the number halfway between 15 and 699, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 699 into our formula, we get:

(15 + 699)/2 = 357

Thus, the number halfway between 15 and 699 is 357.

To check that our answer is correct, we subtract 15 from 357 and subtract 357 from 699 and compare the two numbers:

357 - 15 = 342
699 - 357 = 342

As you can see, the halfway number is 342 higher than 15 and 342 lower than 699. Therefore, our halfway between answer of 357 above is correct.
