Halfway Between 13 and 660

When you ask "What number is halfway between 13 and 660?" 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=660.

Halfway Between Line

To find the number halfway between 13 and 660, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 660 into our formula, we get:

(13 + 660)/2 = 336.5

Thus, the number halfway between 13 and 660 is 336.5.

To check that our answer is correct, we subtract 13 from 336.5 and subtract 336.5 from 660 and compare the two numbers:

336.5 - 13 = 323.5
660 - 336.5 = 323.5

As you can see, the halfway number is 323.5 higher than 13 and 323.5 lower than 660. Therefore, our halfway between answer of 336.5 above is correct.
