Halfway Between 9 and 498

When you ask "What number is halfway between 9 and 498?" 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=498.

Halfway Between Line

To find the number halfway between 9 and 498, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 498 into our formula, we get:

(9 + 498)/2 = 253.5

Thus, the number halfway between 9 and 498 is 253.5.

To check that our answer is correct, we subtract 9 from 253.5 and subtract 253.5 from 498 and compare the two numbers:

253.5 - 9 = 244.5
498 - 253.5 = 244.5

As you can see, the halfway number is 244.5 higher than 9 and 244.5 lower than 498. Therefore, our halfway between answer of 253.5 above is correct.
