Halfway Between 4 and 510

When you ask "What number is halfway between 4 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=4 and Y=510.

Halfway Between Line

To find the number halfway between 4 and 510, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 510 into our formula, we get:

(4 + 510)/2 = 257

Thus, the number halfway between 4 and 510 is 257.

To check that our answer is correct, we subtract 4 from 257 and subtract 257 from 510 and compare the two numbers:

257 - 4 = 253
510 - 257 = 253

As you can see, the halfway number is 253 higher than 4 and 253 lower than 510. Therefore, our halfway between answer of 257 above is correct.
