calculer les 5 premiers termes de la suite
32) tn = √(n+6)
U0 = √6
U1 = √7
U2 = √8 = 2√2
U3 = √9 = 3
U4 = √10
35) U0 = 2 et Un+1 = Un - 4
U1 = U0 - 4 = 2 - 4 = - 2
U2 = U1 - 4 = - 2 - 4 = - 6
U3 = U2 - 4 = - 6 - 4 = - 10
U4 = U3 - 4 = - 10 - 4 = - 14
37) W0 = 1 et Wn+1 = Wn² + 3
W1 = W0² + 3 = 1 + 3 = 4
W2 = W1² + 3 = 19
W3 = W2² + 3 = 364
W4 = W3² + 3 =364² + 3 = 132 499
