a1=1,a(n+1)=3an+2,求an.

数列{an},a1=3,an*a(n+1)=(1/2)^n,求an 已知数列｛an｝中,a(n+1)=an+2^n,a1=3,求an 已知a1=2 a(n+1)=2an+2^n+3^n 求an a(n+1)=2an/3an+4,a1=1/4,求an 数列[An]满足a1=2,a（n+1）=3an-2 求an 在数列{an}中.a1=3且a(n+1)=an^2,求an a(n+1)=an-2*3(n次方)+1,a1=3,求an a1=2,a（n+1）（角标）=an+3n,求an 数列{an}满足a1=2,a(n+1)=2an+n+2,求an 在数列｛an｝中,a1=3,a(n+1)=an+n,求an an中,a1=2,a(n+1)=3an+3(n+1)次方-2n次方,求an 已知数列a1=2,[a(n+1)]=-2[a（n)]+3求an 已知在数列{an}中,a1=2,a(n+1)-3a(n)=3n,求an a1=1,a(n+1)=2an+n^2+2n +2 求an A1=1,A(n+1)/An=(n+2)/n,求An? 已知a1=3,a(n+1)=(3n-1)/(3n+2)an(n≥1),求an a1=3,a(n+1)=an^2求通项公式a1=1,a2=-3,a(n+1)=an+a(n+2)求a2004 1、在数列{an}中,a1=1.a(n+1)=3an+2n+1.求an.2、在数列{an}中,a1=-1,a(n+1)=(3an-4)/[(an)-1].求an.
