In a geometric progression with a common ratio of 4, denoted as $\{b_n\}$, where $T_n$ represents the product of the first $n$ terms of $\{b_n\}$, the fractions $\frac{T_{20}}{T_{10}}$, $\frac{T_{30}}{T_{20}}$, and $\frac{T_{40}}{T_{30}}$ form another geometric sequence with a common ratio of $4^{100}$. Analogously, for an arithmetic sequence $\{a_n\}$ with a common difference of 3, if $S_n$ denotes the sum of the first $n$ terms of $\{a_n\}$, then _____ also form an arithmetic sequence, with a common difference of _____.
