Halfway Between 55 and 487

When you ask "What number is halfway between 55 and 487?" 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=487.

Halfway Between Line

To find the number halfway between 55 and 487, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 487 into our formula, we get:

(55 + 487)/2 = 271

Thus, the number halfway between 55 and 487 is 271.

To check that our answer is correct, we subtract 55 from 271 and subtract 271 from 487 and compare the two numbers:

271 - 55 = 216
487 - 271 = 216

As you can see, the halfway number is 216 higher than 55 and 216 lower than 487. Therefore, our halfway between answer of 271 above is correct.
