Halfway Between 9 and 677

When you ask "What number is halfway between 9 and 677?" 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=677.

Halfway Between Line

To find the number halfway between 9 and 677, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 677 into our formula, we get:

(9 + 677)/2 = 343

Thus, the number halfway between 9 and 677 is 343.

To check that our answer is correct, we subtract 9 from 343 and subtract 343 from 677 and compare the two numbers:

343 - 9 = 334
677 - 343 = 334

As you can see, the halfway number is 334 higher than 9 and 334 lower than 677. Therefore, our halfway between answer of 343 above is correct.
