Halfway Between 25 and 663

When you ask "What number is halfway between 25 and 663?" 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=663.

Halfway Between Line

To find the number halfway between 25 and 663, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 25 and 663 into our formula, we get:

(25 + 663)/2 = 344

Thus, the number halfway between 25 and 663 is 344.

To check that our answer is correct, we subtract 25 from 344 and subtract 344 from 663 and compare the two numbers:

344 - 25 = 319
663 - 344 = 319

As you can see, the halfway number is 319 higher than 25 and 319 lower than 663. Therefore, our halfway between answer of 344 above is correct.
