First term a₁ = -1215 (Given)

…………………………………

Second term a₂ :

`a_(2)=a_(2-1)* (1)/(3) =a_(1)* (1)/(3) =(-1215)/(3) =-405`

…………………………………

Third term a₃ :

`a_(3)=a_(3-1)* (1)/(3) =a_(2)* (1)/(3) =(-405)/(3) =-135`

…………………………………

Fourth term a₄ :

`a_(4)=a_(4-1)* (1)/(3) =a_(3)* (1)/(3) =(-135)/(3) =-45`
