Given an arithmetic sequence $\left\{ a_n \right\}$ with a non-zero common difference, the sum of the first $n$ terms is $S_n$. If $S_{10}=110$, and $\{a_1, a_2, a_4\}$ form a geometric sequence,

(Ⅰ) Find the general formula for the sequence $\left\{ a_n \right\}$;  
(Ⅱ) Let the sequence $\{b_n\}$ satisfy $b_n = \frac{1}{(a_n - 1)(a_n + 1)}$, if the sum of the first $n$ terms of the sequence $\{b_n\}$ is $T_n$, find the value of $T_n$.
