Bài này sai đề . Lấy \(a_1=2;a_2=a_3=a_4=a_5=1\) thay vào thì : 

\(VT=2^2+1^2.4+1=9\) ; \(VP=2\left(1.4+1\right)=10\)  \(\Rightarrow VT< VP\) \(\Rightarrow\) Vô Lí

\(a_1+a_2+a_3+a_4+a_5+a_6+a_7=0\left(1\right)\)

\(a_1+a_2=a_3+a_4=a_5+a_6=a_1+a_7=1\left(2\right)\)

Thay (2) vào (1) : 

\(1+1+1+a_7=0\)

\(\Rightarrow a_7=-3\)

\(a_1=1-a_7=1--3=4\)

\(a_2=1-a_1=1-4=-3\)

Chúc bạn học tốt !!!
