Halfway Between 21 and 571

When you ask "What number is halfway between 21 and 571?" 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=571.

Halfway Between Line

To find the number halfway between 21 and 571, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 571 into our formula, we get:

(21 + 571)/2 = 296

Thus, the number halfway between 21 and 571 is 296.

To check that our answer is correct, we subtract 21 from 296 and subtract 296 from 571 and compare the two numbers:

296 - 21 = 275
571 - 296 = 275

As you can see, the halfway number is 275 higher than 21 and 275 lower than 571. Therefore, our halfway between answer of 296 above is correct.
