Halfway Between 30 and 513

When you ask "What number is halfway between 30 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=30 and Y=513.

Halfway Between Line

To find the number halfway between 30 and 513, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 513 into our formula, we get:

(30 + 513)/2 = 271.5

Thus, the number halfway between 30 and 513 is 271.5.

To check that our answer is correct, we subtract 30 from 271.5 and subtract 271.5 from 513 and compare the two numbers:

271.5 - 30 = 241.5
513 - 271.5 = 241.5

As you can see, the halfway number is 241.5 higher than 30 and 241.5 lower than 513. Therefore, our halfway between answer of 271.5 above is correct.
