Halfway Between 25 and 677




When you ask "What number is halfway between 25 and 677?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=25 and Y=677.



To find the number halfway between 25 and 677, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 25 and 677 into our formula, we get:

(25 + 677)/2 = 351

Thus, the number halfway between 25 and 677 is 351.


To check that our answer is correct, we subtract 25 from 351 and subtract 351 from 677 and compare the two numbers:

351 - 25 = 326
677 - 351 = 326

As you can see, the halfway number is 326 higher than 25 and 326 lower than 677. Therefore, our halfway between answer of 351 above is correct.
