Halfway Between 8 and 678

When you ask "What number is halfway between 8 and 678?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=8 and Y=678.

Halfway Between Line

To find the number halfway between 8 and 678, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 8 and 678 into our formula, we get:

(8 + 678)/2 = 343

Thus, the number halfway between 8 and 678 is 343.

To check that our answer is correct, we subtract 8 from 343 and subtract 343 from 678 and compare the two numbers:

343 - 8 = 335
678 - 343 = 335

As you can see, the halfway number is 335 higher than 8 and 335 lower than 678. Therefore, our halfway between answer of 343 above is correct.
