Halfway Between 100 and 609

When you ask "What number is halfway between 100 and 609?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=100 and Y=609.

Halfway Between Line

To find the number halfway between 100 and 609, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 609 into our formula, we get:

(100 + 609)/2 = 354.5

Thus, the number halfway between 100 and 609 is 354.5.

To check that our answer is correct, we subtract 100 from 354.5 and subtract 354.5 from 609 and compare the two numbers:

354.5 - 100 = 254.5
609 - 354.5 = 254.5

As you can see, the halfway number is 254.5 higher than 100 and 254.5 lower than 609. Therefore, our halfway between answer of 354.5 above is correct.
