Halfway Between 13 and 511

When you ask "What number is halfway between 13 and 511?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=13 and Y=511.

Halfway Between Line

To find the number halfway between 13 and 511, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 511 into our formula, we get:

(13 + 511)/2 = 262

Thus, the number halfway between 13 and 511 is 262.

To check that our answer is correct, we subtract 13 from 262 and subtract 262 from 511 and compare the two numbers:

262 - 13 = 249
511 - 262 = 249

As you can see, the halfway number is 249 higher than 13 and 249 lower than 511. Therefore, our halfway between answer of 262 above is correct.
