Halfway Between 55 and 587

When you ask "What number is halfway between 55 and 587?" 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=587.

Halfway Between Line

To find the number halfway between 55 and 587, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 587 into our formula, we get:

(55 + 587)/2 = 321

Thus, the number halfway between 55 and 587 is 321.

To check that our answer is correct, we subtract 55 from 321 and subtract 321 from 587 and compare the two numbers:

321 - 55 = 266
587 - 321 = 266

As you can see, the halfway number is 266 higher than 55 and 266 lower than 587. Therefore, our halfway between answer of 321 above is correct.
