Halfway Between 8 and 991

When you ask "What number is halfway between 8 and 991?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=8 and Y=991.

Halfway Between Line

To find the number halfway between 8 and 991, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 8 and 991 into our formula, we get:

(8 + 991)/2 = 499.5

Thus, the number halfway between 8 and 991 is 499.5.

To check that our answer is correct, we subtract 8 from 499.5 and subtract 499.5 from 991 and compare the two numbers:

499.5 - 8 = 491.5
991 - 499.5 = 491.5

As you can see, the halfway number is 491.5 higher than 8 and 491.5 lower than 991. Therefore, our halfway between answer of 499.5 above is correct.
