Halfway Between 13 and 998

When you ask "What number is halfway between 13 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=13 and Y=998.

Halfway Between Line

To find the number halfway between 13 and 998, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 998 into our formula, we get:

(13 + 998)/2 = 505.5

Thus, the number halfway between 13 and 998 is 505.5.

To check that our answer is correct, we subtract 13 from 505.5 and subtract 505.5 from 998 and compare the two numbers:

505.5 - 13 = 492.5
998 - 505.5 = 492.5

As you can see, the halfway number is 492.5 higher than 13 and 492.5 lower than 998. Therefore, our halfway between answer of 505.5 above is correct.
