Halfway Between 17 and 485

When you ask "What number is halfway between 17 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=17 and Y=485.

Halfway Between Line

To find the number halfway between 17 and 485, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 485 into our formula, we get:

(17 + 485)/2 = 251

Thus, the number halfway between 17 and 485 is 251.

To check that our answer is correct, we subtract 17 from 251 and subtract 251 from 485 and compare the two numbers:

251 - 17 = 234
485 - 251 = 234

As you can see, the halfway number is 234 higher than 17 and 234 lower than 485. Therefore, our halfway between answer of 251 above is correct.
