若数列{an｝满足a1=2且an+an-1=2的n次方+2的n-1次方,Sn为数列｛an｝的前n项和,则log2（S2012+2)=

数列｛an｝满足a1=1,且an=an-1+3n-2,求an 若数列{an}满足a1=1,a2=5且an+2=an+1-an,求a2000 关于数列、等差数列的题目设数列an满足an+1=an-2且a1=241）判断an是什么数列2）若an 数列an满足,a1=8且8an+1an-16an+1+2an+5=0 已知数列{an}满足An+1=2^nAn,且A1=1,则通项an 已知数列an满足an=1+2+...+n,且1/a1+1/a2+...+1/an 若数列an满足a1=1,且an+1=an/1+an.证明:数列1/an为等差数列,并求出数列an的通项公 若数列{an}的项满足[(an-an-1)-3](an+an-1)=0,且a1=2,则a2005的最小值为? 数列[An]满足An+1-An+3=0,且A1=-5.求An. 已知数列{an}中满足(An+1-An)(An+1+An)=16,且a1=1,an 数列{An}满足a1=1/2,a1+a2+..+an=n方an,求an 已知数列an满足an+1/an=n+2/n且a1=1,则an= 已知数列,an满足a1=1,a3+a7=18,且an-1+an+1=2an 已知数列{an}满足,an+2=an+1-an,且a10=-1,a9=0,求a1 数列{an}满足a1=a,an+1=1+1/an.若3/2 数列{An}满足Sn=n^2An,若A1=1005,求An的表达式? 已知递增数列{an}满足a1=1,(2an+1)=an+(an+2),且a1,a2,a4成等比数列.求an 已知数列an满足:an+1-2an=2^n+1,且a1=2 (1)证明{an/2^n}是等差数列 (2)求数列an的
