Halfway Between 5 and 511

When you ask "What number is halfway between 5 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=5 and Y=511.

Halfway Between Line

To find the number halfway between 5 and 511, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 511 into our formula, we get:

(5 + 511)/2 = 258

Thus, the number halfway between 5 and 511 is 258.

To check that our answer is correct, we subtract 5 from 258 and subtract 258 from 511 and compare the two numbers:

258 - 5 = 253
511 - 258 = 253

As you can see, the halfway number is 253 higher than 5 and 253 lower than 511. Therefore, our halfway between answer of 258 above is correct.
