Halfway Between 1 and 520

When you ask "What number is halfway between 1 and 520?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=1 and Y=520.

Halfway Between Line

To find the number halfway between 1 and 520, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 520 into our formula, we get:

(1 + 520)/2 = 260.5

Thus, the number halfway between 1 and 520 is 260.5.

To check that our answer is correct, we subtract 1 from 260.5 and subtract 260.5 from 520 and compare the two numbers:

260.5 - 1 = 259.5
520 - 260.5 = 259.5

As you can see, the halfway number is 259.5 higher than 1 and 259.5 lower than 520. Therefore, our halfway between answer of 260.5 above is correct.
