Halfway Between 28 and 990

When you ask "What number is halfway between 28 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=28 and Y=990.

Halfway Between Line

To find the number halfway between 28 and 990, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 28 and 990 into our formula, we get:

(28 + 990)/2 = 509

Thus, the number halfway between 28 and 990 is 509.

To check that our answer is correct, we subtract 28 from 509 and subtract 509 from 990 and compare the two numbers:

509 - 28 = 481
990 - 509 = 481

As you can see, the halfway number is 481 higher than 28 and 481 lower than 990. Therefore, our halfway between answer of 509 above is correct.
