Halfway Between 15 and 987

When you ask "What number is halfway between 15 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=15 and Y=987.

Halfway Between Line

To find the number halfway between 15 and 987, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 987 into our formula, we get:

(15 + 987)/2 = 501

Thus, the number halfway between 15 and 987 is 501.

To check that our answer is correct, we subtract 15 from 501 and subtract 501 from 987 and compare the two numbers:

501 - 15 = 486
987 - 501 = 486

As you can see, the halfway number is 486 higher than 15 and 486 lower than 987. Therefore, our halfway between answer of 501 above is correct.
