Problem 571

Soit {Un}\left\{U_{n}\right\} et (Vn)\left(V_{n}\right) deux suites définies par: Un=2n+4n+32U_{n}=\frac{2^{n}+4 n+3}{2} et Vn=2n4n+32V_{n}=\frac{2^{n}-4 n+3}{2} On pose T1=Un+VnT_{1}=U_{n}+V_{n} et T2=UnVnT_{2}=U_{n}-V_{n} 1) Montrer que T1T_{1} est géométrique et que T2T_{2} est arithmétique ? 2) En déduire S1S_{1} et S2S_{2} en fonction de nn tels que: S1=K=0nUKS_{1}=\sum_{K=0}^{n} \boldsymbol{U}_{K} et S2=K=0nVKS_{2}=\sum_{K=0}^{n} V_{K}
