Halfway Between 13 and 709

When you ask "What number is halfway between 13 and 709?" 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=709.

Halfway Between Line

To find the number halfway between 13 and 709, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 709 into our formula, we get:

(13 + 709)/2 = 361

Thus, the number halfway between 13 and 709 is 361.

To check that our answer is correct, we subtract 13 from 361 and subtract 361 from 709 and compare the two numbers:

361 - 13 = 348
709 - 361 = 348

As you can see, the halfway number is 348 higher than 13 and 348 lower than 709. Therefore, our halfway between answer of 361 above is correct.
