Halfway Between 28 and 840

When you ask "What number is halfway between 28 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=28 and Y=840.

Halfway Between Line

To find the number halfway between 28 and 840, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 28 and 840 into our formula, we get:

(28 + 840)/2 = 434

Thus, the number halfway between 28 and 840 is 434.

To check that our answer is correct, we subtract 28 from 434 and subtract 434 from 840 and compare the two numbers:

434 - 28 = 406
840 - 434 = 406

As you can see, the halfway number is 406 higher than 28 and 406 lower than 840. Therefore, our halfway between answer of 434 above is correct.
