已知差数列{a}满足:A1=14,An+1=An-2/3(n属于正整数),则使An*An+2已知差数列{a}满足:A1=14,An+1=An-2/3(n属于正整数),则使An*An+2已知差数列{a}

已知差数列{a}满足:A1=14,An+1=An-2/3(n属于正整数),则使An*An+2
已知差数列{a}满足:A1=14,An+1=An-2/3(n属于正整数),则使An*An+2

已知差数列{a}满足:A1=14,An+1=An-2/3(n属于正整数),则使An*An+2
由题意的:等差数列的公差为-2/3
所以通项为an=14*(-2/3)*(n-1)=44/3-2/3n
An*An+2
