Exercice 1 On place un capital de 3000 euros à \( 2 \% \) par an, à intérêts simples, On rappelle le principe du placement à intérêts simples : à la fin de chaque année, les intérêts sont calculés uniquement sur le capital initialément placé. On modélise le capital acquis tous les ans par une suite \( \left(\mathrm{C}_{n}\right) \). Ainsi on pose : \( \mathrm{C}_{0}=3000 \), 1. Calculer le capital \( \mathrm{C}_{1} \) acquis à la fin de la première année, et \( \mathrm{C}_{2} \) à la fin de la deuxième année. 2. En écrivant une relation de récurrence liant \( \mathrm{C}_{n+1} \) et \( \mathrm{C}_{n} \), démontrer que la suite \( \left(\mathrm{C}_{n}\right) \) modélisant le capital est une suite arithmétique, dont on précisera la raison et le premier terme. 3. A l'aide de la calculatrice, calculer \( \mathrm{C}_{10} \). Que représente cette valeur?
