Halfway Between 100 and 603

When you ask "What number is halfway between 100 and 603?" 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=603.

Halfway Between Line

To find the number halfway between 100 and 603, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 603 into our formula, we get:

(100 + 603)/2 = 351.5

Thus, the number halfway between 100 and 603 is 351.5.

To check that our answer is correct, we subtract 100 from 351.5 and subtract 351.5 from 603 and compare the two numbers:

351.5 - 100 = 251.5
603 - 351.5 = 251.5

As you can see, the halfway number is 251.5 higher than 100 and 251.5 lower than 603. Therefore, our halfway between answer of 351.5 above is correct.
