All rings are commutative rings with identity, and $J(R)$ denotes the Jacobson radical of the ring $R$. For any fixed integer $n\geq 1$, it is shown that the class of all $n$-stable rings is properly contained in the class of all $n+1$-stable rings. Results are given showing the connection between several types of rings whose finite sequences satisfy different stability conditions, some involving $J(R)$. It is shown that in the strongly $n$-stable case, it suffices to check whether the $n+1$-tuples satisfy the stable condition. In addition to other results and an example of a ring which is not $n$-stable for any integer $n\geq 1$, examples are given to show the distinction between the different types of stability cases. Finally, in the last section, some surjective mapping properties of a generalized form of $GL_{n}(R)$ and $SL_{n}(R)$ in connection to some stable conditions in the ring $R$ are investigated.
