$ {a_0}=2,$
$ {a_n}=2012+{a_0}{a_1}{a_2}{a_3}...{a_{n-2}}{a_{n-1}} $ .
Find out $ {a_{2012}} $.

Re: AN INTERESTING PROBLEM BY SAKAL DA
The answer is:
$a_{2012}=2012+2^{2^{2011}}$
$a_{2012}=2012+2^{2^{2011}}$

Re: AN INTERESTING PROBLEM BY SAKAL DA
Let $b_n=a_n-2012$ notice that $a_n$ depends totally on $a_{n-1}$.$a_{n-1}-2012=a_n(a_n-2012)$
So $b_{n+1}=b_n(b_n+2012)$
Then the general formula can be established using induction.I see no better way right now.
So $b_{n+1}=b_n(b_n+2012)$
