Halfway Between 13 and 782

When you ask "What number is halfway between 13 and 782?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=13 and Y=782.

Halfway Between Line

To find the number halfway between 13 and 782, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 782 into our formula, we get:

(13 + 782)/2 = 397.5

Thus, the number halfway between 13 and 782 is 397.5.

To check that our answer is correct, we subtract 13 from 397.5 and subtract 397.5 from 782 and compare the two numbers:

397.5 - 13 = 384.5
782 - 397.5 = 384.5

As you can see, the halfway number is 384.5 higher than 13 and 384.5 lower than 782. Therefore, our halfway between answer of 397.5 above is correct.
