So there's a sequence: 0, 1/2, 3/4, 7/8, 15/16,... and I have to find the pattern and the next two numbers. I don't understand how I should go about doing this. I don't believe it uses multiplication or division as it starts with 0. Help?

Do you understand what the different "places" are? And is it tens or tenths? There's a difference. Tens is like 10, 20, 30, 40, and so on, and tenths is like 3.1, 3.2, and 3.4, where .1 and .2 and .4 are in the tenths place.

When adding radicals, do you add two radicands together even if they're different? How would you answer this equation in radical simplest form? 3 rad 12 + 3 rad 12 + 5 rad 8 +5 rad 8 I got 6 rad 12 + 25 rad 8 Is this right? Sorry if my questions are confusing, this is hard...
