数列满足前N项和为Sn,且Sn=3/2(an-1),bn=1/4bn-1-3/4(n大于等于2)且b1=3求An,Bn通

数列an的前n项和为Sn,Sn=4an-3,①证明an是等比数列②数列bn满足b1=2,bn+1=an+bn.求数列bn 设数列an前n项和为Sn,且an+Sn=1,求an的通项公式 若数列bn满足b1=1且bn+1=bn+an,求数列bn通 3.设数列{an}的前n项和Sn=2an-4(n∈N+),数列{bn}满足:bn+1=an+2bn,且b1=2.求{bn 若数列{an]满足前n项和Sn=2an-4,bn+1=an+2bn,且b1=2,求:bn;{bn}的前n项和Tn 已知数列an满足bn=an-3n,且bn为等比数列,求an前n项和Sn 数列an前n项和为sn,a1=1,数列bn首项b1=2,且sn+n^2=n(an+1),bn=abn-1求an,bn的通 an=2*3^n-1 若数列bn满足bn=an+（-1）^n*ln（an）,求数列bn前n项和Sn 数列an的前n项和为Sn,Sn=2an-1,数列bn满足b1=2,bn+1=an+bn.求数列bn的前n项和Tn 数列{an}的前n项和Sn=2an-1(n≥1）,数列{bn}满足b1=3,b(n+1)=an+bn,求数列{bn}的前 已知数列{an}的前n项和为Sn，且Sn=2an-2，数列{bn}满足b1=1，且bn+1=bn+2． 数列[an]的前n项和Sn等于2an-1,数列[bn]满足：b1=3,bn+1=an+bn,n属于N*.1.证明数列[a 已知数列an满足;a1=1,an+1-an=1,数列bn的前n项和为sn,且sn+bn=2
