Halfway Between 12 and 840

When you ask "What number is halfway between 12 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=12 and Y=840.

Halfway Between Line

To find the number halfway between 12 and 840, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 12 and 840 into our formula, we get:

(12 + 840)/2 = 426

Thus, the number halfway between 12 and 840 is 426.

To check that our answer is correct, we subtract 12 from 426 and subtract 426 from 840 and compare the two numbers:

426 - 12 = 414
840 - 426 = 414

As you can see, the halfway number is 414 higher than 12 and 414 lower than 840. Therefore, our halfway between answer of 426 above is correct.
