Halfway Between 55 and 491

When you ask "What number is halfway between 55 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=55 and Y=491.

Halfway Between Line

To find the number halfway between 55 and 491, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 491 into our formula, we get:

(55 + 491)/2 = 273

Thus, the number halfway between 55 and 491 is 273.

To check that our answer is correct, we subtract 55 from 273 and subtract 273 from 491 and compare the two numbers:

273 - 55 = 218
491 - 273 = 218

As you can see, the halfway number is 218 higher than 55 and 218 lower than 491. Therefore, our halfway between answer of 273 above is correct.
