Halfway Between 1 and 510

When you ask "What number is halfway between 1 and 510?" 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=510.

Halfway Between Line

To find the number halfway between 1 and 510, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 510 into our formula, we get:

(1 + 510)/2 = 255.5

Thus, the number halfway between 1 and 510 is 255.5.

To check that our answer is correct, we subtract 1 from 255.5 and subtract 255.5 from 510 and compare the two numbers:

255.5 - 1 = 254.5
510 - 255.5 = 254.5

As you can see, the halfway number is 254.5 higher than 1 and 254.5 lower than 510. Therefore, our halfway between answer of 255.5 above is correct.
