Halfway Between 87 and 987

When you ask "What number is halfway between 87 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=87 and Y=987.

Halfway Between Line

To find the number halfway between 87 and 987, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 87 and 987 into our formula, we get:

(87 + 987)/2 = 537

Thus, the number halfway between 87 and 987 is 537.

To check that our answer is correct, we subtract 87 from 537 and subtract 537 from 987 and compare the two numbers:

537 - 87 = 450
987 - 537 = 450

As you can see, the halfway number is 450 higher than 87 and 450 lower than 987. Therefore, our halfway between answer of 537 above is correct.
