Halfway Between 2 and 678

When you ask "What number is halfway between 2 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=2 and Y=678.

Halfway Between Line

To find the number halfway between 2 and 678, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 2 and 678 into our formula, we get:

(2 + 678)/2 = 340

Thus, the number halfway between 2 and 678 is 340.

To check that our answer is correct, we subtract 2 from 340 and subtract 340 from 678 and compare the two numbers:

340 - 2 = 338
678 - 340 = 338

As you can see, the halfway number is 338 higher than 2 and 338 lower than 678. Therefore, our halfway between answer of 340 above is correct.
