Halfway Between 31 and 987

When you ask "What number is halfway between 31 and 987?" 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=987.

Halfway Between Line

To find the number halfway between 31 and 987, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 31 and 987 into our formula, we get:

(31 + 987)/2 = 509

Thus, the number halfway between 31 and 987 is 509.

To check that our answer is correct, we subtract 31 from 509 and subtract 509 from 987 and compare the two numbers:

509 - 31 = 478
987 - 509 = 478

As you can see, the halfway number is 478 higher than 31 and 478 lower than 987. Therefore, our halfway between answer of 509 above is correct.
