{an}等差数列,{bn}等比数列,公差公比均为d,且a1=b1,a3=3b3,a5=5b5,求{an}和{bn}?

{an}等差数列,{bn}等比数列,公差公比均为d,且a1=b1,a3=3b3,a5=5b5,求{an}和{bn}? 已知等差数列{an}的公差和等比数列{bn}的公比都是d(d≠1）,且a1=b1,a3=3b3,a5=5b5,求a1和d 等差数列an的公差和等比数列bn的公比相等,且都等于d(d>0）d不等于0,若a1=b1,a3=5b3,a5=5b5求a 已知等差数列的公差与等比数列的公比相等,且都等于d,又知a1=b1,a3=3b3,a5=5b5,求an,bn 数列｛an｝是等差数列,{bn}是正项等比数列,且a1=b1=1,a3+b5=21,a5+b3=13,求{an}和{bn 设公差为非零的等差数列{An}与等比数列{Bn},满足A1=B1,A3=B3,A7=B5,求公比q 在等比数列an和公差不为0的等差数列bn中,a1=b1>0,a3=b3>0,比较a2与b2,a5与b5 设{an}是等差数列,{bn}是各项都为正数的等比数列且a1=b1=1,a3+b5=21,a5+b3=13.求{an}, 设{an}是等差数列,{bn}是各项都为正数的等比数列且a1=b1=1,a3+b5=21,a5+b3=13.求[an}, 设{an}是等差数列,{bn}是各项都为正数的等比数列,且a1=b1=1,a3+b5=21,a5+b3=13,求{an} 已知数列[an]为等差数列,公差d≠0;[bn]为等比数列,公比为q,若a1=b1,a3=b3,a7=b5,且an=bm 设{an}是等差数列,{bn}是各项都为正数的等比数列,且a1=b1=1,a3+b5=21,a5+b3=13 (1)求{
