Q:
19 Une entreprise compte 23 salariés en fin d'année
2010. Durant l'année, le nombre de ses salariés
double, mais en fin d'année, 22 salariés quittent
l'entreprise.
On note \( s_{n} \) le nombre de salariés fin \( 2010+n \).
a) Écrire une relation de récurrence entre \( s_{n+1} \)
et \( s_{n} \).
b) À l'aide d'une calculatrice, calculer le nombre de
salariés de proche en proche, jusqu'en fin 2020 .
