Salut!
Formezi ecuatia 2000 = 435,5 + 10s, unde s reprezinta pretul unui scaun.
O rezolvam: 1564,5 = 10s => s = 156,45 lei.
Bafta!

Hello,

$
u_{4}= 12+(4-4)*\frac{1}{4}\\

u_{3}= 12+(3-4)*\frac{1}{4} \\

u_{2}= 12+(2-4)*\frac{1}{4} \\

u_{1}= 12+ (1-4)*\frac{1}{4} \\

u_{5}= 12+ (5-4)*\frac{1}{4} \\

u_{6}= 12+ (6-4)*\frac{1}{4} \\
...\\

\boxed{u_{n}= 12+ (n-4)*\frac{1}{4}} \\
