Halfway Between 65 and 510

When you ask "What number is halfway between 65 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=65 and Y=510.

Halfway Between Line

To find the number halfway between 65 and 510, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 65 and 510 into our formula, we get:

(65 + 510)/2 = 287.5

Thus, the number halfway between 65 and 510 is 287.5.

To check that our answer is correct, we subtract 65 from 287.5 and subtract 287.5 from 510 and compare the two numbers:

287.5 - 65 = 222.5
510 - 287.5 = 222.5

As you can see, the halfway number is 222.5 higher than 65 and 222.5 lower than 510. Therefore, our halfway between answer of 287.5 above is correct.
