Halfway Between 21 and 699

When you ask "What number is halfway between 21 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=21 and Y=699.

Halfway Between Line

To find the number halfway between 21 and 699, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 699 into our formula, we get:

(21 + 699)/2 = 360

Thus, the number halfway between 21 and 699 is 360.

To check that our answer is correct, we subtract 21 from 360 and subtract 360 from 699 and compare the two numbers:

360 - 21 = 339
699 - 360 = 339

As you can see, the halfway number is 339 higher than 21 and 339 lower than 699. Therefore, our halfway between answer of 360 above is correct.
