Halfway Between 21 and 705

When you ask "What number is halfway between 21 and 705?" 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=705.

Halfway Between Line

To find the number halfway between 21 and 705, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 705 into our formula, we get:

(21 + 705)/2 = 363

Thus, the number halfway between 21 and 705 is 363.

To check that our answer is correct, we subtract 21 from 363 and subtract 363 from 705 and compare the two numbers:

363 - 21 = 342
705 - 363 = 342

As you can see, the halfway number is 342 higher than 21 and 342 lower than 705. Therefore, our halfway between answer of 363 above is correct.
