Bonsoir,
1)
Z = 3
A = Z - 1 = 3 - 1 = 2
B = A² = 2² = 4
C = Z + 1 = 3 + 1 = 4
D = C² = 4² = 16
Z = B + D = 4 + 16 = 20
Donc Z = 20.
2)
Z = 3
Z = Z - 1 = 3 - 1 = 2
A = Z² = 2² = 4
Z = Z + 1 = 2 + 1 = 3 #On garde la dernière valeur de Z.
B = Z² = 3² = 9
Z = A + B = 4 + 9 = 13
Donc Z = 13.
3)
Z = 3
Z = Z - 1 = 3 - 1 = 2
B = Z² = 2² = 4
A = Z + 1 = 2 + 1 = 3
C = A² = 3² = 9
Z = B + C = 4 + 9 = 13
Donc Z = 13.
Bonne soirée,
Thomas
