Suites arithmétiques Les questions sont indépendantes. 1. On définit pour tout \( n \) la suite \( \left(U_{n}\right) \) par : \[ U_{n}=3 n-2 \] Montrer que \( \left(U_{n}\right) \) est une suite arithmétique. 2. Soit \( \left(U_{n}\right) \) une suite arithmétique de premier terme \( U_{0}=5 \) et de raison \( \frac{1}{3} \). Calculer le \( 9^{\text {ieme terme, puis calculer la }} \) somme : \( S=U_{0}+U_{1}+U_{2}+\ldots+U_{8} \)
