Halfway Between 31 and 780

When you ask "What number is halfway between 31 and 780?" 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=780.

Halfway Between Line

To find the number halfway between 31 and 780, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 31 and 780 into our formula, we get:

(31 + 780)/2 = 405.5

Thus, the number halfway between 31 and 780 is 405.5.

To check that our answer is correct, we subtract 31 from 405.5 and subtract 405.5 from 780 and compare the two numbers:

405.5 - 31 = 374.5
780 - 405.5 = 374.5

As you can see, the halfway number is 374.5 higher than 31 and 374.5 lower than 780. Therefore, our halfway between answer of 405.5 above is correct.
