Halfway Between 25 and 665

When you ask "What number is halfway between 25 and 665?" 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=665.

Halfway Between Line

To find the number halfway between 25 and 665, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 25 and 665 into our formula, we get:

(25 + 665)/2 = 345

Thus, the number halfway between 25 and 665 is 345.

To check that our answer is correct, we subtract 25 from 345 and subtract 345 from 665 and compare the two numbers:

345 - 25 = 320
665 - 345 = 320

As you can see, the halfway number is 320 higher than 25 and 320 lower than 665. Therefore, our halfway between answer of 345 above is correct.
