Halfway Between 1 and 990

When you ask "What number is halfway between 1 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=1 and Y=990.

Halfway Between Line

To find the number halfway between 1 and 990, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 990 into our formula, we get:

(1 + 990)/2 = 495.5

Thus, the number halfway between 1 and 990 is 495.5.

To check that our answer is correct, we subtract 1 from 495.5 and subtract 495.5 from 990 and compare the two numbers:

495.5 - 1 = 494.5
990 - 495.5 = 494.5

As you can see, the halfway number is 494.5 higher than 1 and 494.5 lower than 990. Therefore, our halfway between answer of 495.5 above is correct.
