数列｛an｝满足a1=1,且an=an-1+3n-2,求an

数列｛an｝满足a1=1,且an=an-1+3n-2,求an 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=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=an+1 -lg2,且a1=1,则通项公式为? 已知数列an满足an=1+2+...+n,且1/a1+1/a2+...+1/an 已知数列{an}满足：an+1=an+n,且a61=2002,则a1等于 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 已知数列{an}满足a1=1 an+1=an/(3an+1) 则球an 已知数列[an]满足An+1=1+an /3-an ,且a1=1/3,求证数列[1/(an -1）]是等差数列,并求an 数列{An}满足a1=1/2,a1+a2+..+an=n方an,求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+1/an=n+2/n且a1=1,则an= 若数列{an}满足a1=1,a2=5且an+2=an+1-an,求a2000 已知数列{an}满足,an+2=an+1-an,且a10=-1,a9=0,求a1 已知数列｛an｝满足a1=4/3,且an+1=4（n+1）an/3an+n 数列{an]满足a1=1且an+1=an+3n次方,求an通项公式
