Halfway Between 25 and 555

When you ask "What number is halfway between 25 and 555?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=25 and Y=555.

Halfway Between Line

To find the number halfway between 25 and 555, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 25 and 555 into our formula, we get:

(25 + 555)/2 = 290

Thus, the number halfway between 25 and 555 is 290.

To check that our answer is correct, we subtract 25 from 290 and subtract 290 from 555 and compare the two numbers:

290 - 25 = 265
555 - 290 = 265

As you can see, the halfway number is 265 higher than 25 and 265 lower than 555. Therefore, our halfway between answer of 290 above is correct.
