数列[An]满足a1=2,a（n+1）=3an-2 求an

数列[An]满足a1=2,a（n+1）=3an-2 求an 数列{an}满足a1=2,a(n+1)=2an+n+2,求an 已知数列an满足a1=2,an=a(n-1)+2n,（n≥2）,求an 已知数列{an}满足a1=33,a（n+1）-an=2n,求an/n的最小值 已知数列{an}满足a1=2,a(n+1)-an=a(n+1）*an,则a31=? 已知数列{a}满足a1=1/2,a（n+1）=an+1/(n^2+n),求an已知数列{a}满足a1=1/2,a（n+1）=an+1/(n^2+n),求an 在数列an中,a1=1,且满足a（n+1）=3an +2n,求an 已知数列an满足条件a1=-2 a（n+1）=2an/(1-an) 则an= 数列an满足a1=1,a(n+1)=an/[(2an)+1],求a2010 已知数列｛An｝满足a1=1,a（n+1）=2an+1 求证数列{an+1}是等比数列 求数列｛an｝通式 若数列an满足a1=1,an+1=2^nan...若数列an满足a1=1,a（n+1）=2^n·an,则数列an的通项公式? 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,且an-a（n-1）=2n.求a2,a3,a4.求数列｛an｝通项an 已知数列{an}满足：a1=1,an=a1+2a2+3a3+``````+(n-1)a(n-1)(n大于等于2）,则通项公式an是什么? 已知数列｛an｝满足a1=2,a(n+1)=1+an/1-an（n∈N*）,a1*a2*a3*...*a2010的值为 数列{an}满足a1=2,a(n+1)=-1/(an+1),则a2010等于 数列｛an｝满足a1=3,a n+1=2an,则a4等于 已知数列{an}满足a1=1,a(n+1)=2an+1.求证（1）数列a(n+1)是等比数列；（2）求an
