Halfway Between 100 and 910

When you ask "What number is halfway between 100 and 910?" 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=910.

Halfway Between Line

To find the number halfway between 100 and 910, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 910 into our formula, we get:

(100 + 910)/2 = 505

Thus, the number halfway between 100 and 910 is 505.

To check that our answer is correct, we subtract 100 from 505 and subtract 505 from 910 and compare the two numbers:

505 - 100 = 405
910 - 505 = 405

As you can see, the halfway number is 405 higher than 100 and 405 lower than 910. Therefore, our halfway between answer of 505 above is correct.
