Halfway Between 8 and 669

When you ask "What number is halfway between 8 and 669?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=8 and Y=669.

Halfway Between Line

To find the number halfway between 8 and 669, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 8 and 669 into our formula, we get:

(8 + 669)/2 = 338.5

Thus, the number halfway between 8 and 669 is 338.5.

To check that our answer is correct, we subtract 8 from 338.5 and subtract 338.5 from 669 and compare the two numbers:

338.5 - 8 = 330.5
669 - 338.5 = 330.5

As you can see, the halfway number is 330.5 higher than 8 and 330.5 lower than 669. Therefore, our halfway between answer of 338.5 above is correct.
