Halfway Between 4 and 990

When you ask "What number is halfway between 4 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=4 and Y=990.

Halfway Between Line

To find the number halfway between 4 and 990, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 990 into our formula, we get:

(4 + 990)/2 = 497

Thus, the number halfway between 4 and 990 is 497.

To check that our answer is correct, we subtract 4 from 497 and subtract 497 from 990 and compare the two numbers:

497 - 4 = 493
990 - 497 = 493

As you can see, the halfway number is 493 higher than 4 and 493 lower than 990. Therefore, our halfway between answer of 497 above is correct.
