Halfway Between 9 and 491

When you ask "What number is halfway between 9 and 491?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=9 and Y=491.

Halfway Between Line

To find the number halfway between 9 and 491, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 491 into our formula, we get:

(9 + 491)/2 = 250

Thus, the number halfway between 9 and 491 is 250.

To check that our answer is correct, we subtract 9 from 250 and subtract 250 from 491 and compare the two numbers:

250 - 9 = 241
491 - 250 = 241

As you can see, the halfway number is 241 higher than 9 and 241 lower than 491. Therefore, our halfway between answer of 250 above is correct.
