Halfway Between 15 and 540

When you ask "What number is halfway between 15 and 540?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=15 and Y=540.

Halfway Between Line

To find the number halfway between 15 and 540, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 540 into our formula, we get:

(15 + 540)/2 = 277.5

Thus, the number halfway between 15 and 540 is 277.5.

To check that our answer is correct, we subtract 15 from 277.5 and subtract 277.5 from 540 and compare the two numbers:

277.5 - 15 = 262.5
540 - 277.5 = 262.5

As you can see, the halfway number is 262.5 higher than 15 and 262.5 lower than 540. Therefore, our halfway between answer of 277.5 above is correct.
