Halfway Between 17 and 491

When you ask "What number is halfway between 17 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=17 and Y=491.

Halfway Between Line

To find the number halfway between 17 and 491, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 491 into our formula, we get:

(17 + 491)/2 = 254

Thus, the number halfway between 17 and 491 is 254.

To check that our answer is correct, we subtract 17 from 254 and subtract 254 from 491 and compare the two numbers:

254 - 17 = 237
491 - 254 = 237

As you can see, the halfway number is 237 higher than 17 and 237 lower than 491. Therefore, our halfway between answer of 254 above is correct.
