Halfway Between 20 and 998

When you ask "What number is halfway between 20 and 998?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=20 and Y=998.

Halfway Between Line

To find the number halfway between 20 and 998, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 998 into our formula, we get:

(20 + 998)/2 = 509

Thus, the number halfway between 20 and 998 is 509.

To check that our answer is correct, we subtract 20 from 509 and subtract 509 from 998 and compare the two numbers:

509 - 20 = 489
998 - 509 = 489

As you can see, the halfway number is 489 higher than 20 and 489 lower than 998. Therefore, our halfway between answer of 509 above is correct.
