Halfway Between 21 and 979

When you ask "What number is halfway between 21 and 979?" 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=979.

Halfway Between Line

To find the number halfway between 21 and 979, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 979 into our formula, we get:

(21 + 979)/2 = 500

Thus, the number halfway between 21 and 979 is 500.

To check that our answer is correct, we subtract 21 from 500 and subtract 500 from 979 and compare the two numbers:

500 - 21 = 479
979 - 500 = 479

As you can see, the halfway number is 479 higher than 21 and 479 lower than 979. Therefore, our halfway between answer of 500 above is correct.
