Halfway Between 12 and 510

When you ask "What number is halfway between 12 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=12 and Y=510.

Halfway Between Line

To find the number halfway between 12 and 510, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 12 and 510 into our formula, we get:

(12 + 510)/2 = 261

Thus, the number halfway between 12 and 510 is 261.

To check that our answer is correct, we subtract 12 from 261 and subtract 261 from 510 and compare the two numbers:

261 - 12 = 249
510 - 261 = 249

As you can see, the halfway number is 249 higher than 12 and 249 lower than 510. Therefore, our halfway between answer of 261 above is correct.
