Halfway Between 2 and 840

When you ask "What number is halfway between 2 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=2 and Y=840.

Halfway Between Line

To find the number halfway between 2 and 840, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 2 and 840 into our formula, we get:

(2 + 840)/2 = 421

Thus, the number halfway between 2 and 840 is 421.

To check that our answer is correct, we subtract 2 from 421 and subtract 421 from 840 and compare the two numbers:

421 - 2 = 419
840 - 421 = 419

As you can see, the halfway number is 419 higher than 2 and 419 lower than 840. Therefore, our halfway between answer of 421 above is correct.
