Halfway Between 45 and 515

When you ask "What number is halfway between 45 and 515?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=45 and Y=515.

Halfway Between Line

To find the number halfway between 45 and 515, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 515 into our formula, we get:

(45 + 515)/2 = 280

Thus, the number halfway between 45 and 515 is 280.

To check that our answer is correct, we subtract 45 from 280 and subtract 280 from 515 and compare the two numbers:

280 - 45 = 235
515 - 280 = 235

As you can see, the halfway number is 235 higher than 45 and 235 lower than 515. Therefore, our halfway between answer of 280 above is correct.
