Exercice 11: L'objectif de cet exercice est l'étude de la suite \( \left(u_{n}\right) \) définie pour tout entier \( n \) par : \[ \left\{\begin{array}{c}u_{0}=3 \\ u_{n+1}=\frac{4 u_{n}-2}{u_{n}+1}\end{array}\right. \] 1. Etudier les variations de la fonction \( f \) définie sur \( ] 1 ;+\infty\left[\right. \) par \( f(x)=\frac{4 x-2}{x+1} \) 2. Démontrer par récurrence que pour tout entier naturel \( n, u_{n}>2 \) 3. Etudier le sens de variation de la suite. 4. Montrer que pour tout entier naturel \( n, u_{n+1}-2=\frac{2}{u_{n}+1}\left(u_{n}-2\right) \). En déduire que pour tout entier naturel \( n, u_{n+1}-2<\frac{2}{3}\left(u_{n}-2\right) \) 5. Démontrer par récurrence que pour tout entier naturel \( n, 0 \leq u_{n}-2 \leq\left(\frac{2}{3}\right)^{n} \) 6. En déduire la limite éventuelle de la suite.
