Halfway Between 31 and 40

When you ask "What number is halfway between 31 and 40?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=31 and Y=40.

Halfway Between Line

To find the number halfway between 31 and 40, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 31 and 40 into our formula, we get:

(31 + 40)/2 = 35.5

Thus, the number halfway between 31 and 40 is 35.5.

To check that our answer is correct, we subtract 31 from 35.5 and subtract 35.5 from 40 and compare the two numbers:

35.5 - 31 = 4.5
40 - 35.5 = 4.5

As you can see, the halfway number is 4.5 higher than 31 and 4.5 lower than 40. Therefore, our halfway between answer of 35.5 above is correct.
