Halfway Between 40 and 840

When you ask "What number is halfway between 40 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=40 and Y=840.

Halfway Between Line

To find the number halfway between 40 and 840, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 840 into our formula, we get:

(40 + 840)/2 = 440

Thus, the number halfway between 40 and 840 is 440.

To check that our answer is correct, we subtract 40 from 440 and subtract 440 from 840 and compare the two numbers:

440 - 40 = 400
840 - 440 = 400

As you can see, the halfway number is 400 higher than 40 and 400 lower than 840. Therefore, our halfway between answer of 440 above is correct.
