To find the next three terms of the sequence: 36, 12, 4, we will first determine if this sequence is a geometric progression (GP) and then calculate the next terms. Step 1: Identify the first three termsLet:- t1=36- t2=12- t3=4 Step 2: Check if the sequence is a GPTo check ...
解析 Solution: (A). The general term of the sequence can be written as: a_n=2/(n(n+1)) which can be decomposed into two parts a_n=2(1/n-1/(n+1)) . Let n =1,2,3,… S_n=2(1-1/2+1/2-1/3+⋯+1/n-1/(n+1)) =2(1-1/(n+1))=(2n)/(n+1) ...
