Halfway Between 10 and 510

When you ask "What number is halfway between 10 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=10 and Y=510.

Halfway Between Line

To find the number halfway between 10 and 510, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 10 and 510 into our formula, we get:

(10 + 510)/2 = 260

Thus, the number halfway between 10 and 510 is 260.

To check that our answer is correct, we subtract 10 from 260 and subtract 260 from 510 and compare the two numbers:

260 - 10 = 250
510 - 260 = 250

As you can see, the halfway number is 250 higher than 10 and 250 lower than 510. Therefore, our halfway between answer of 260 above is correct.
