Halfway Between 43 and 990

When you ask "What number is halfway between 43 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=43 and Y=990.

Halfway Between Line

To find the number halfway between 43 and 990, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 43 and 990 into our formula, we get:

(43 + 990)/2 = 516.5

Thus, the number halfway between 43 and 990 is 516.5.

To check that our answer is correct, we subtract 43 from 516.5 and subtract 516.5 from 990 and compare the two numbers:

516.5 - 43 = 473.5
990 - 516.5 = 473.5

As you can see, the halfway number is 473.5 higher than 43 and 473.5 lower than 990. Therefore, our halfway between answer of 516.5 above is correct.
