Halfway Between 43 and 678

When you ask "What number is halfway between 43 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=43 and Y=678.

Halfway Between Line

To find the number halfway between 43 and 678, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 43 and 678 into our formula, we get:

(43 + 678)/2 = 360.5

Thus, the number halfway between 43 and 678 is 360.5.

To check that our answer is correct, we subtract 43 from 360.5 and subtract 360.5 from 678 and compare the two numbers:

360.5 - 43 = 317.5
678 - 360.5 = 317.5

As you can see, the halfway number is 317.5 higher than 43 and 317.5 lower than 678. Therefore, our halfway between answer of 360.5 above is correct.
