Halfway Between 90 and 510

When you ask "What number is halfway between 90 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=90 and Y=510.

Halfway Between Line

To find the number halfway between 90 and 510, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 510 into our formula, we get:

(90 + 510)/2 = 300

Thus, the number halfway between 90 and 510 is 300.

To check that our answer is correct, we subtract 90 from 300 and subtract 300 from 510 and compare the two numbers:

300 - 90 = 210
510 - 300 = 210

As you can see, the halfway number is 210 higher than 90 and 210 lower than 510. Therefore, our halfway between answer of 300 above is correct.
