Halfway Between 78 and 513

When you ask "What number is halfway between 78 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=78 and Y=513.

Halfway Between Line

To find the number halfway between 78 and 513, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 513 into our formula, we get:

(78 + 513)/2 = 295.5

Thus, the number halfway between 78 and 513 is 295.5.

To check that our answer is correct, we subtract 78 from 295.5 and subtract 295.5 from 513 and compare the two numbers:

295.5 - 78 = 217.5
513 - 295.5 = 217.5

As you can see, the halfway number is 217.5 higher than 78 and 217.5 lower than 513. Therefore, our halfway between answer of 295.5 above is correct.
