Halfway Between 18 and 980

When you ask "What number is halfway between 18 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=18 and Y=980.

Halfway Between Line

To find the number halfway between 18 and 980, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 18 and 980 into our formula, we get:

(18 + 980)/2 = 499

Thus, the number halfway between 18 and 980 is 499.

To check that our answer is correct, we subtract 18 from 499 and subtract 499 from 980 and compare the two numbers:

499 - 18 = 481
980 - 499 = 481

As you can see, the halfway number is 481 higher than 18 and 481 lower than 980. Therefore, our halfway between answer of 499 above is correct.
