Halfway Between 21 and 980

When you ask "What number is halfway between 21 and 980?" 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=980.

Halfway Between Line

To find the number halfway between 21 and 980, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 980 into our formula, we get:

(21 + 980)/2 = 500.5

Thus, the number halfway between 21 and 980 is 500.5.

To check that our answer is correct, we subtract 21 from 500.5 and subtract 500.5 from 980 and compare the two numbers:

500.5 - 21 = 479.5
980 - 500.5 = 479.5

As you can see, the halfway number is 479.5 higher than 21 and 479.5 lower than 980. Therefore, our halfway between answer of 500.5 above is correct.
