Halfway Between 17 and 997

When you ask "What number is halfway between 17 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=17 and Y=997.

Halfway Between Line

To find the number halfway between 17 and 997, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 997 into our formula, we get:

(17 + 997)/2 = 507

Thus, the number halfway between 17 and 997 is 507.

To check that our answer is correct, we subtract 17 from 507 and subtract 507 from 997 and compare the two numbers:

507 - 17 = 490
997 - 507 = 490

As you can see, the halfway number is 490 higher than 17 and 490 lower than 997. Therefore, our halfway between answer of 507 above is correct.
