Halfway Between 13 and 670

When you ask "What number is halfway between 13 and 670?" 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=670.

Halfway Between Line

To find the number halfway between 13 and 670, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 670 into our formula, we get:

(13 + 670)/2 = 341.5

Thus, the number halfway between 13 and 670 is 341.5.

To check that our answer is correct, we subtract 13 from 341.5 and subtract 341.5 from 670 and compare the two numbers:

341.5 - 13 = 328.5
670 - 341.5 = 328.5

As you can see, the halfway number is 328.5 higher than 13 and 328.5 lower than 670. Therefore, our halfway between answer of 341.5 above is correct.
