Halfway Between 100 and 998

When you ask "What number is halfway between 100 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=100 and Y=998.

Halfway Between Line

To find the number halfway between 100 and 998, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 998 into our formula, we get:

(100 + 998)/2 = 549

Thus, the number halfway between 100 and 998 is 549.

To check that our answer is correct, we subtract 100 from 549 and subtract 549 from 998 and compare the two numbers:

549 - 100 = 449
998 - 549 = 449

As you can see, the halfway number is 449 higher than 100 and 449 lower than 998. Therefore, our halfway between answer of 549 above is correct.
