Halfway Between 9 and 797

When you ask "What number is halfway between 9 and 797?" 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=797.

Halfway Between Line

To find the number halfway between 9 and 797, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 797 into our formula, we get:

(9 + 797)/2 = 403

Thus, the number halfway between 9 and 797 is 403.

To check that our answer is correct, we subtract 9 from 403 and subtract 403 from 797 and compare the two numbers:

403 - 9 = 394
797 - 403 = 394

As you can see, the halfway number is 394 higher than 9 and 394 lower than 797. Therefore, our halfway between answer of 403 above is correct.
