Bonjour,
v₀ = 4/9 ; vₙ₊₁ = 3/2 vₙ
v₁ = 3/2 v₀ = 3/2 × 4/9 = 2/3
v₂ = 3/2 v₁ = 3/2 × 2/3 = 1
v₃ = 3/2 v₂ = 3/2 × 1 =3/2
v₄ = 3/2 × v₃ = 3/2 × 3/2 = 9/4

Bonjour
vous pouvez m'aidez à compléter la 2ème colonne?

Explications étape par étape :
v1 = 3v0/2 = 3/2 x 4/9 = 2/3
v2 = 3/2) x v1 = 3/2 x 2/3 = 1
v3 = 3/2) x v2 = 3/2 x 1 = 3/2
v4 = 3/2) x v3 = 3/2 x 3/2 = 9/4
