17.已知数列{an}中.a1=$\frac{1}{3}$.an+1=$\frac{{a} {n}}{2-{a} {n}}$求证:数列{$\frac{1}{{a} {n}}$-1}是等比数列.并求{an}的通项公式an,(2)设bn=$\frac{n{a} {n}}{1-{a} {n}}$.求证:$\sum {i=1}^{n}{b} {i}$<2.
解答解:(1)数列{an}的前n项和Sn满足:Sn=2(an-1), 当n=1时,a1=S1=2(a1-1),解得a1=2, 当n>1时,an=Sn-Sn-1=2(an-1)-2(an-1-1), 化简可得an=2an-1, 由等比数列的通项公式,可得an=2n, 数列{bn}满足:对任意n∈N*有∑ni=1∑i=1naibi=(n-1)•2n+1+2. ...
