Halfway Between 9 and 485

When you ask "What number is halfway between 9 and 485?" 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=485.

Halfway Between Line

To find the number halfway between 9 and 485, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 485 into our formula, we get:

(9 + 485)/2 = 247

Thus, the number halfway between 9 and 485 is 247.

To check that our answer is correct, we subtract 9 from 247 and subtract 247 from 485 and compare the two numbers:

247 - 9 = 238
485 - 247 = 238

As you can see, the halfway number is 238 higher than 9 and 238 lower than 485. Therefore, our halfway between answer of 247 above is correct.
