1.

a prend la valeur n - 2

b prend la valeur a.n

c prend la valeur b + 1

Afficher c

2.

a) n = 5:

a = n - 2 = 5 - 2 = 3

b = a x n = 3 x 5 = 15

c = b + 1 = 15 +1 = 16

Si n = 5 on obtiendra le résultat 16.

b) n = 3:

a = n - 2 = 3 - 2 = 1

b = a x n = 1 x 3 = 3

c = b + 1 = 3 + 1 = 4

Si n = 3 on obtiendra le résultat 4.

c) n = 1:

a = n - 2 = 1 - 2 = -1

b = a x n = 1 x -1 = -1

c = b + 1 = -1 + 1 = 0

Si n = 1 on obtiendra le résultat 0.

d) n = 4:

a = n - 2 = 4 - 2 = 2

b = a x n = 4 x 2 = 8

c = b + 1 = 8 + 1 = 9

Si n = 4 on obtiendra le résultat 9.
