When you ask "What number is halfway between 100 and 689?" 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=689.
To find the number halfway between 100 and 689, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 100 and 689 into our formula, we get:
(100 + 689)/2 = 394.5
Thus, the number halfway between 100 and 689 is 394.5.
To check that our answer is correct, we subtract 100 from 394.5 and subtract 394.5 from 689 and compare the two numbers:
394.5 - 100 = 294.5
689 - 394.5 = 294.5
As you can see, the halfway number is 294.5 higher than 100 and 294.5 lower than 689. Therefore, our halfway between answer of 394.5 above is correct.
