Given the function $$f(x)= \frac {3}{2}x+\ln(x-1)$$, let the sequence $\{a_n\}$ satisfy the following two conditions: ① $a_{n}>0$ ($n\in\mathbb{N}^{*}$); ② $a_{n+1}=f′(a_{n}+1)$.  
(Ⅰ) Express $a_{n+1}$ in terms of $a_n$;  
(Ⅱ) Let $b_{n}=a_{2n}$ ($n\in\mathbb{N}^{*}$), if the sequence $\{b_n\}$ is decreasing, find the range of values for $a_1$.
