Halfway Between 100 and 730

When you ask "What number is halfway between 100 and 730?" 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=730.

Halfway Between Line

To find the number halfway between 100 and 730, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 730 into our formula, we get:

(100 + 730)/2 = 415

Thus, the number halfway between 100 and 730 is 415.

To check that our answer is correct, we subtract 100 from 415 and subtract 415 from 730 and compare the two numbers:

415 - 100 = 315
730 - 415 = 315

As you can see, the halfway number is 315 higher than 100 and 315 lower than 730. Therefore, our halfway between answer of 415 above is correct.
