Halfway Between 25 and 425

When you ask "What number is halfway between 25 and 425?" 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=425.

Halfway Between Line

To find the number halfway between 25 and 425, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 25 and 425 into our formula, we get:

(25 + 425)/2 = 225

Thus, the number halfway between 25 and 425 is 225.

To check that our answer is correct, we subtract 25 from 225 and subtract 225 from 425 and compare the two numbers:

225 - 25 = 200
425 - 225 = 200

As you can see, the halfway number is 200 higher than 25 and 200 lower than 425. Therefore, our halfway between answer of 225 above is correct.
