Halfway Between 0 and 550

When you ask "What number is halfway between 0 and 550?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=0 and Y=550.

Halfway Between Line

To find the number halfway between 0 and 550, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 0 and 550 into our formula, we get:

(0 + 550)/2 = 275

Thus, the number halfway between 0 and 550 is 275.

To check that our answer is correct, we subtract 0 from 275 and subtract 275 from 550 and compare the two numbers:

275 - 0 = 275
550 - 275 = 275

As you can see, the halfway number is 275 higher than 0 and 275 lower than 550. Therefore, our halfway between answer of 275 above is correct.
