Halfway Between 10 and 550

When you ask "What number is halfway between 10 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=10 and Y=550.

Halfway Between Line

To find the number halfway between 10 and 550, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 10 and 550 into our formula, we get:

(10 + 550)/2 = 280

Thus, the number halfway between 10 and 550 is 280.

To check that our answer is correct, we subtract 10 from 280 and subtract 280 from 550 and compare the two numbers:

280 - 10 = 270
550 - 280 = 270

As you can see, the halfway number is 270 higher than 10 and 270 lower than 550. Therefore, our halfway between answer of 280 above is correct.
