Halfway Between 40 and 678

When you ask "What number is halfway between 40 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=40 and Y=678.

Halfway Between Line

To find the number halfway between 40 and 678, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 678 into our formula, we get:

(40 + 678)/2 = 359

Thus, the number halfway between 40 and 678 is 359.

To check that our answer is correct, we subtract 40 from 359 and subtract 359 from 678 and compare the two numbers:

359 - 40 = 319
678 - 359 = 319

As you can see, the halfway number is 319 higher than 40 and 319 lower than 678. Therefore, our halfway between answer of 359 above is correct.
