Halfway Between 42 and 990

When you ask "What number is halfway between 42 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=42 and Y=990.

Halfway Between Line

To find the number halfway between 42 and 990, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 42 and 990 into our formula, we get:

(42 + 990)/2 = 516

Thus, the number halfway between 42 and 990 is 516.

To check that our answer is correct, we subtract 42 from 516 and subtract 516 from 990 and compare the two numbers:

516 - 42 = 474
990 - 516 = 474

As you can see, the halfway number is 474 higher than 42 and 474 lower than 990. Therefore, our halfway between answer of 516 above is correct.
