Sagot :

Bonjour,

T0 = T de 1950 = 20 000

Tₙ = T de ( 1950+n)

Tₙ = T de (n-1) - 1%

ex : T2 = T de (2-1) - 1% = T1 - 1%

1.

T1 = (T1-1) - 1% = T0 - 1% = 20 000 - 1% = 20000 - 200 = 19 800

T2 = (T2-1) - 1% = T1 - 1% = 19800 - 1% = 19800 - 198 = 19602

T3 = T(3-2) - 1% = T2 - 1% = 19602 - 1% = 19602 - 196,02 = 19405,98

2.

Tn+1 = Tn - 1%

3.

la suite doit se faire avec un tableur

Bonne journée
