Halfway Between 3 and 510

When you ask "What number is halfway between 3 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=3 and Y=510.

Halfway Between Line

To find the number halfway between 3 and 510, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 3 and 510 into our formula, we get:

(3 + 510)/2 = 256.5

Thus, the number halfway between 3 and 510 is 256.5.

To check that our answer is correct, we subtract 3 from 256.5 and subtract 256.5 from 510 and compare the two numbers:

256.5 - 3 = 253.5
510 - 256.5 = 253.5

As you can see, the halfway number is 253.5 higher than 3 and 253.5 lower than 510. Therefore, our halfway between answer of 256.5 above is correct.
