Halfway Between 89 and 513

When you ask "What number is halfway between 89 and 513?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=89 and Y=513.

Halfway Between Line

To find the number halfway between 89 and 513, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 513 into our formula, we get:

(89 + 513)/2 = 301

Thus, the number halfway between 89 and 513 is 301.

To check that our answer is correct, we subtract 89 from 301 and subtract 301 from 513 and compare the two numbers:

301 - 89 = 212
513 - 301 = 212

As you can see, the halfway number is 212 higher than 89 and 212 lower than 513. Therefore, our halfway between answer of 301 above is correct.
