Halfway Between 30 and 997

When you ask "What number is halfway between 30 and 997?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=30 and Y=997.

Halfway Between Line

To find the number halfway between 30 and 997, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 997 into our formula, we get:

(30 + 997)/2 = 513.5

Thus, the number halfway between 30 and 997 is 513.5.

To check that our answer is correct, we subtract 30 from 513.5 and subtract 513.5 from 997 and compare the two numbers:

513.5 - 30 = 483.5
997 - 513.5 = 483.5

As you can see, the halfway number is 483.5 higher than 30 and 483.5 lower than 997. Therefore, our halfway between answer of 513.5 above is correct.
