Halfway Between 40 and 513

When you ask "What number is halfway between 40 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=40 and Y=513.

Halfway Between Line

To find the number halfway between 40 and 513, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 513 into our formula, we get:

(40 + 513)/2 = 276.5

Thus, the number halfway between 40 and 513 is 276.5.

To check that our answer is correct, we subtract 40 from 276.5 and subtract 276.5 from 513 and compare the two numbers:

276.5 - 40 = 236.5
513 - 276.5 = 236.5

As you can see, the halfway number is 236.5 higher than 40 and 236.5 lower than 513. Therefore, our halfway between answer of 276.5 above is correct.
