Halfway Between 13 and 691

When you ask "What number is halfway between 13 and 691?" 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=691.

Halfway Between Line

To find the number halfway between 13 and 691, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 691 into our formula, we get:

(13 + 691)/2 = 352

Thus, the number halfway between 13 and 691 is 352.

To check that our answer is correct, we subtract 13 from 352 and subtract 352 from 691 and compare the two numbers:

352 - 13 = 339
691 - 352 = 339

As you can see, the halfway number is 339 higher than 13 and 339 lower than 691. Therefore, our halfway between answer of 352 above is correct.
