Halfway Between 9 and 425

When you ask "What number is halfway between 9 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=9 and Y=425.

Halfway Between Line

To find the number halfway between 9 and 425, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 425 into our formula, we get:

(9 + 425)/2 = 217

Thus, the number halfway between 9 and 425 is 217.

To check that our answer is correct, we subtract 9 from 217 and subtract 217 from 425 and compare the two numbers:

217 - 9 = 208
425 - 217 = 208

As you can see, the halfway number is 208 higher than 9 and 208 lower than 425. Therefore, our halfway between answer of 217 above is correct.
