Halfway Between 17 and 555

When you ask "What number is halfway between 17 and 555?" 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=555.

Halfway Between Line

To find the number halfway between 17 and 555, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 555 into our formula, we get:

(17 + 555)/2 = 286

Thus, the number halfway between 17 and 555 is 286.

To check that our answer is correct, we subtract 17 from 286 and subtract 286 from 555 and compare the two numbers:

286 - 17 = 269
555 - 286 = 269

As you can see, the halfway number is 269 higher than 17 and 269 lower than 555. Therefore, our halfway between answer of 286 above is correct.
