Halfway Between 21 and 747

When you ask "What number is halfway between 21 and 747?" 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=747.

Halfway Between Line

To find the number halfway between 21 and 747, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 747 into our formula, we get:

(21 + 747)/2 = 384

Thus, the number halfway between 21 and 747 is 384.

To check that our answer is correct, we subtract 21 from 384 and subtract 384 from 747 and compare the two numbers:

384 - 21 = 363
747 - 384 = 363

As you can see, the halfway number is 363 higher than 21 and 363 lower than 747. Therefore, our halfway between answer of 384 above is correct.
