### Re: Dhaka Secondary 2009/5

*Mahi* wrote:$a_n=2+a_0 \cdot a_1 \cdot a_2 \cdot a_3 \cdots a_{n-1}$ So $a_n-2=a_0 \cdot a_1 \cdot a_2 \cdot a_3 \cdots a_{n-1}$
Or, $a_{n}(a_n-2)+2=2+a_0 \cdot a_1 \cdot a_2 \cdot a_3 \cdots a_{n-1} \cdot a_n = a_{n+1}$
but how can we get $a_{2009}$ from this equation?
