Halfway Between 5 and 840




When you ask "What number is halfway between 5 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=5 and Y=840.



To find the number halfway between 5 and 840, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 840 into our formula, we get:

(5 + 840)/2 = 422.5

Thus, the number halfway between 5 and 840 is 422.5.


To check that our answer is correct, we subtract 5 from 422.5 and subtract 422.5 from 840 and compare the two numbers:

422.5 - 5 = 417.5
840 - 422.5 = 417.5

As you can see, the halfway number is 417.5 higher than 5 and 417.5 lower than 840. Therefore, our halfway between answer of 422.5 above is correct.
