Halfway Between 4 and 840

When you ask "What number is halfway between 4 and 840?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=4 and Y=840.

Halfway Between Line

To find the number halfway between 4 and 840, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 840 into our formula, we get:

(4 + 840)/2 = 422

Thus, the number halfway between 4 and 840 is 422.

To check that our answer is correct, we subtract 4 from 422 and subtract 422 from 840 and compare the two numbers:

422 - 4 = 418
840 - 422 = 418

As you can see, the halfway number is 418 higher than 4 and 418 lower than 840. Therefore, our halfway between answer of 422 above is correct.
