Halfway Between 88 and 990

When you ask "What number is halfway between 88 and 990?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=88 and Y=990.

Halfway Between Line

To find the number halfway between 88 and 990, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 88 and 990 into our formula, we get:

(88 + 990)/2 = 539

Thus, the number halfway between 88 and 990 is 539.

To check that our answer is correct, we subtract 88 from 539 and subtract 539 from 990 and compare the two numbers:

539 - 88 = 451
990 - 539 = 451

As you can see, the halfway number is 451 higher than 88 and 451 lower than 990. Therefore, our halfway between answer of 539 above is correct.
