Is finding the next term in the sequence the problem or is finding the "expression for $a_n$ what's giving you trouble?

anonymous · Answer

the whole thing confuses me and i don't think i really get any of it.

anonymous · Answer

I've looked at the example but I'm not getting why there are so many different equations and know when to use which one

Ok. 

So let's take the first sequence: 

4/3,-5/4, 6/5,-7/6…

To write it another way: 

+4/3
-5/4 
+6/5
-7/6
...
What comes next?

anonymous · Answer

to know the different i would do -7/6-(6/5) and so on right?
