Halfway Between 100 and 605

When you ask "What number is halfway between 100 and 605?" 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=605.

Halfway Between Line

To find the number halfway between 100 and 605, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 605 into our formula, we get:

(100 + 605)/2 = 352.5

Thus, the number halfway between 100 and 605 is 352.5.

To check that our answer is correct, we subtract 100 from 352.5 and subtract 352.5 from 605 and compare the two numbers:

352.5 - 100 = 252.5
605 - 352.5 = 252.5

As you can see, the halfway number is 252.5 higher than 100 and 252.5 lower than 605. Therefore, our halfway between answer of 352.5 above is correct.
