at first was a little bit confused about what An-1 meant but third example gave me more understanding of what to do

Daler,
Im glad you got more understanding. An-1 simply put, is the previous term.

Mr. Estrada I understand the concept and what were doing it, but my only question is why do we substitute the previous term to the equation to find the next term when it says n-1, is n-1 the previous term. And will it say something other then n-1, for example like n-3 or n-10.

Jurgen,
Those are great questions!
First you asked:
"my only question is why do we substitute the previous term to the equation to find the next term when it says n-1, is n-1 the previous term[?]"
Correct n-1 is the previous term.

Then you asked:
"will it say something other then n-1, for example like n-3 or n-10.[?]"
I would suppose that it can say something like n-3, in that case they would have to give you 3 terms to begin
eg:
a1= 3
a2= 5
a3= 6
an= an-1 + an-3

In the example above a4= 6 +3, which is 9 a5= 9 +5, which is 14. and so on to get the rest

I think the arithmetic and the geometric formula are kinda similar to the recursive formula.
