Halfway Between 21 and 591

When you ask "What number is halfway between 21 and 591?" 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=591.

Halfway Between Line

To find the number halfway between 21 and 591, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 591 into our formula, we get:

(21 + 591)/2 = 306

Thus, the number halfway between 21 and 591 is 306.

To check that our answer is correct, we subtract 21 from 306 and subtract 306 from 591 and compare the two numbers:

306 - 21 = 285
591 - 306 = 285

As you can see, the halfway number is 285 higher than 21 and 285 lower than 591. Therefore, our halfway between answer of 306 above is correct.
