Halfway Between 84 and 510

When you ask "What number is halfway between 84 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=84 and Y=510.

Halfway Between Line

To find the number halfway between 84 and 510, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 84 and 510 into our formula, we get:

(84 + 510)/2 = 297

Thus, the number halfway between 84 and 510 is 297.

To check that our answer is correct, we subtract 84 from 297 and subtract 297 from 510 and compare the two numbers:

297 - 84 = 213
510 - 297 = 213

As you can see, the halfway number is 213 higher than 84 and 213 lower than 510. Therefore, our halfway between answer of 297 above is correct.
