Halfway Between 17 and 669

When you ask "What number is halfway between 17 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=17 and Y=669.

Halfway Between Line

To find the number halfway between 17 and 669, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 669 into our formula, we get:

(17 + 669)/2 = 343

Thus, the number halfway between 17 and 669 is 343.

To check that our answer is correct, we subtract 17 from 343 and subtract 343 from 669 and compare the two numbers:

343 - 17 = 326
669 - 343 = 326

As you can see, the halfway number is 326 higher than 17 and 326 lower than 669. Therefore, our halfway between answer of 343 above is correct.
