Halfway Between 55 and 517

When you ask "What number is halfway between 55 and 517?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=55 and Y=517.

Halfway Between Line

To find the number halfway between 55 and 517, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 517 into our formula, we get:

(55 + 517)/2 = 286

Thus, the number halfway between 55 and 517 is 286.

To check that our answer is correct, we subtract 55 from 286 and subtract 286 from 517 and compare the two numbers:

286 - 55 = 231
517 - 286 = 231

As you can see, the halfway number is 231 higher than 55 and 231 lower than 517. Therefore, our halfway between answer of 286 above is correct.
