Halfway Between 2 and 509

When you ask "What number is halfway between 2 and 509?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=2 and Y=509.

Halfway Between Line

To find the number halfway between 2 and 509, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 2 and 509 into our formula, we get:

(2 + 509)/2 = 255.5

Thus, the number halfway between 2 and 509 is 255.5.

To check that our answer is correct, we subtract 2 from 255.5 and subtract 255.5 from 509 and compare the two numbers:

255.5 - 2 = 253.5
509 - 255.5 = 253.5

As you can see, the halfway number is 253.5 higher than 2 and 253.5 lower than 509. Therefore, our halfway between answer of 255.5 above is correct.
