Halfway Between 21 and 570

When you ask "What number is halfway between 21 and 570?" 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=570.

Halfway Between Line

To find the number halfway between 21 and 570, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 570 into our formula, we get:

(21 + 570)/2 = 295.5

Thus, the number halfway between 21 and 570 is 295.5.

To check that our answer is correct, we subtract 21 from 295.5 and subtract 295.5 from 570 and compare the two numbers:

295.5 - 21 = 274.5
570 - 295.5 = 274.5

As you can see, the halfway number is 274.5 higher than 21 and 274.5 lower than 570. Therefore, our halfway between answer of 295.5 above is correct.
