Halfway Between 8 and 510

When you ask "What number is halfway between 8 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=8 and Y=510.

Halfway Between Line

To find the number halfway between 8 and 510, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 8 and 510 into our formula, we get:

(8 + 510)/2 = 259

Thus, the number halfway between 8 and 510 is 259.

To check that our answer is correct, we subtract 8 from 259 and subtract 259 from 510 and compare the two numbers:

259 - 8 = 251
510 - 259 = 251

As you can see, the halfway number is 251 higher than 8 and 251 lower than 510. Therefore, our halfway between answer of 259 above is correct.
