Halfway Between 100 and 830

When you ask "What number is halfway between 100 and 830?" 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=830.

Halfway Between Line

To find the number halfway between 100 and 830, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 830 into our formula, we get:

(100 + 830)/2 = 465

Thus, the number halfway between 100 and 830 is 465.

To check that our answer is correct, we subtract 100 from 465 and subtract 465 from 830 and compare the two numbers:

465 - 100 = 365
830 - 465 = 365

As you can see, the halfway number is 365 higher than 100 and 365 lower than 830. Therefore, our halfway between answer of 465 above is correct.
