等比数列｛an｝满足AnAn=16∧n,则公比是多少?

若等比数列{an}满足anan+1=16^n 等比数列｛an｝满足AnAn=16∧n,则公比是多少? 等比数列｛an｝满足AnAn+1=16∧n,则公比是?（n+1都是右下角的） 若等比数列{an}满足anan+1=16^n,则公比是? 若等比数列{an}满足anan+1=16^n则公比为? 等比数列{an}满足anan+1=16*n则公比为 若等比数列｛an}满足anan+1=16*n,则公式为n是小n，问题是--则公比为 等比数列练习题：若等比数列{An}满足AnAn+1=16,求公比? 若等比数列{an}满足anan+1=16^n,则公比为A.2B.4C.8D16n和n+1都为小写下标…… 在数列{An}中,An小于0（n属于正整数）,数列{AnAn+1}是公比为q的等比数列,且满足2AnAn+1+An+1An+2>An+2An+3,则公比Q的取值范围? 数列an满足a1=2 ,a2=1,且( an-1 -an )/anan-1 =(an -an+1 )/anan+1 (n大于等于2),求a100 = 已知数列An中,A1=1,AnAn+1=(1/2)^n,1)求证{an}为等比数列 已知数列{an}满足a1=1,anan+1=2^n,则a9+a10 若等差数列an满足anan+1=n2+3n+2,则公差为? 若等差数列﹛an﹜满足anan+1=n2+3n+2,则公差为 已知数列{an}满足条件：a1=1,a2=r,且数列{anan+1}是公比为q的等比数列.设bn =a（2n-1）+a（2n）（） 已知{an}是等比数列,a2=2,a5=1/4,则a1a2+a2a3+```anan+1=已知{an}是等比数列,a2=2,a5=1/4,则a1a2+a2a3+```anan+1=?A.16(1-1/4^n)B.16(1-2^n)C.32/3(1-1/4^n)D.32/3(1-1/2^n) 已知｛an｝是等比数列,其通项公式为an=2·3^(n-1)(n∈N+)则anan+2=?,（an）^2=?
