1. Calcul des premiers termes : \[ \begin{aligned} u_0 &= 8\;;& \\ u_1 &= qu_0 = 1,35 \times 8 = 10,8\;;& \\ u_2 &= qu_1 = 1,35\times 10,8 = 14,58\;;& \\ u_3 &= qu_2 = 1,35\times 14,58 = 19,683.& \end{aligned}\]

2. Calcul des premiers termes : \[ \begin{aligned} u_0 &= -0,5\;;& \\ u_1 &= qu_0 = 0,6 \times (-0,5) = -0,3\;;& \\ u_2 &= qu_1 = 0,6 \times (-0,3) = -0,18\;;& \\ u_3 &= qu_2 = 0,6 \times (-0,18) = -0,108.& \end{aligned} \]
