数列an,bn满足anbn=1,an=n²+3n+2,则bn的前十项之和是?
数列{an} ,{bn}满足anbn = 1,an = n2 + 3n + 2,则{bn}的前十项的和为
数列{an},{bn}满足anbn=1,an=n*n(n的平方)+3n+2,则{bn}的前10项之和为()
数列an,bn满足anbn=1,an=n^2+3n+2,则bn的前n项之和为
数列{an}、{bn}满足an•bn=1,an=n2+3n+2,则{bn}的前10项之和等于( )
已知:an=3n-1,bn=2^n,求数列{anbn}的前n项和
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
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
已知数列{an}的前n项和Sn=2^n-1,若bn=n.求数列{anbn}的前n项和Tn
已知数列an中,a1=2,an+1=an+2(n属于N*)数列bn满足bn=1/anan+1,求bn前十项和
已知数列{an}的前n项和Sn=3×(3/2)^(n-1)-1,数列{bn}满足bn=a(n+1)/log3/2(an+
已知数列{an},如果数列{bn}满足b1=a1,bn=an+a(n-1)则称数列{bn}是数列{an}的生成数列
