Halfway Between 65 and 990

When you ask "What number is halfway between 65 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=65 and Y=990.

Halfway Between Line

To find the number halfway between 65 and 990, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 65 and 990 into our formula, we get:

(65 + 990)/2 = 527.5

Thus, the number halfway between 65 and 990 is 527.5.

To check that our answer is correct, we subtract 65 from 527.5 and subtract 527.5 from 990 and compare the two numbers:

527.5 - 65 = 462.5
990 - 527.5 = 462.5

As you can see, the halfway number is 462.5 higher than 65 and 462.5 lower than 990. Therefore, our halfway between answer of 527.5 above is correct.
