Halfway Between 21 and 707

When you ask "What number is halfway between 21 and 707?" 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=707.

Halfway Between Line

To find the number halfway between 21 and 707, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 707 into our formula, we get:

(21 + 707)/2 = 364

Thus, the number halfway between 21 and 707 is 364.

To check that our answer is correct, we subtract 21 from 364 and subtract 364 from 707 and compare the two numbers:

364 - 21 = 343
707 - 364 = 343

As you can see, the halfway number is 343 higher than 21 and 343 lower than 707. Therefore, our halfway between answer of 364 above is correct.
