Halfway Between 5 and 685

When you ask "What number is halfway between 5 and 685?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=5 and Y=685.

Halfway Between Line

To find the number halfway between 5 and 685, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 685 into our formula, we get:

(5 + 685)/2 = 345

Thus, the number halfway between 5 and 685 is 345.

To check that our answer is correct, we subtract 5 from 345 and subtract 345 from 685 and compare the two numbers:

345 - 5 = 340
685 - 345 = 340

As you can see, the halfway number is 340 higher than 5 and 340 lower than 685. Therefore, our halfway between answer of 345 above is correct.
