Halfway Between 55 and 501

When you ask "What number is halfway between 55 and 501?" 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=501.

Halfway Between Line

To find the number halfway between 55 and 501, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 501 into our formula, we get:

(55 + 501)/2 = 278

Thus, the number halfway between 55 and 501 is 278.

To check that our answer is correct, we subtract 55 from 278 and subtract 278 from 501 and compare the two numbers:

278 - 55 = 223
501 - 278 = 223

As you can see, the halfway number is 223 higher than 55 and 223 lower than 501. Therefore, our halfway between answer of 278 above is correct.
