Halfway Between 100 and 693

When you ask "What number is halfway between 100 and 693?" 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=693.

Halfway Between Line

To find the number halfway between 100 and 693, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 693 into our formula, we get:

(100 + 693)/2 = 396.5

Thus, the number halfway between 100 and 693 is 396.5.

To check that our answer is correct, we subtract 100 from 396.5 and subtract 396.5 from 693 and compare the two numbers:

396.5 - 100 = 296.5
693 - 396.5 = 296.5

As you can see, the halfway number is 296.5 higher than 100 and 296.5 lower than 693. Therefore, our halfway between answer of 396.5 above is correct.
