等差数列有如下性质,若数列{an}是等差数列,则当bn=a1+a2+…+ann(n∈N*)时,数列{bn}也是等差数列;类比上述性质,相应地{cn}是正项等比数列,当数... -
22794诸类
：[答案] 由数列{an}是等差数列,则当bn= a1+a2+…+an n(n∈N*)时,数列{bn}也是等差数列. 类比得到:{cn}是正项等比数列,当数列dn=(c1c2…cn) 1 n时,数列{dn}也是等比数列. 证明如下: ∵{cn}是正项等比数列,设其公比为q, ∴(c1c2…cn) 1 n=(c1nq1+...

根据下列条件,写出数列的前四项,并归纳猜想它的通项公式:①a1=1,an+1=an+ann+1(n∈N*)②a1= - 1,an+1=an+1n(n+1)(n∈N*) -
22794诸类
：[答案] ①∵a1=1,an+1=an+ an n+1, ∴a2=a1+ a1 1+1= 3 2,∴a3=a2+ a2 2+1=2, 同理可得a4= 5 2,猜想an= n+1 2; ②∵a1=-1,an+1=an+ 1 n(n+1), ∴a2=a1+ 1 1*2=- 1 2,∴a3=a2+ 1 2*3=- 1 3, 同理可得a4=- 1 4,猜想an=- 1 n

一道求数列通项公式的问题2An+1=An+1/Ann+1是下标2A(n+1)=A(n)+1/A(n) -
22794诸类
：[答案] 2A(n+1)+2 = An + 1/An + 2 = (An^2 + 2An + 1)/An 2A(n+1)-2 = An + 1/An - 2 = (An^2 - 2An + 1)/An => (A(n+1)+1)/(A(n+1)-1) = ((An+1)/(An-1))^2 设bn = (An+1)/(An-1) => b(n+1)=bn^2 => lgb(n+1)=2lgbn => lgbn = 2^(n-1)lgb1 => bn = b1*10^(2^(n-1)) ...
