Halfway Between 45 and 669

When you ask "What number is halfway between 45 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=45 and Y=669.

Halfway Between Line

To find the number halfway between 45 and 669, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 669 into our formula, we get:

(45 + 669)/2 = 357

Thus, the number halfway between 45 and 669 is 357.

To check that our answer is correct, we subtract 45 from 357 and subtract 357 from 669 and compare the two numbers:

357 - 45 = 312
669 - 357 = 312

As you can see, the halfway number is 312 higher than 45 and 312 lower than 669. Therefore, our halfway between answer of 357 above is correct.
