Question

Fill in the table with the next four terms of the sequence a1=4 and an=3an – 1, if n≥2.

Answer 1

Answer:

12, 36, 108, 324

Step-by-step explanation:

using the recursive formula and a₁ = 4 , then

a₂ = 3a₁ = 3 × 4 = 12

a₃ = 3a₂ = 3 × 12 = 36

a₄ = 3a₃ = 3 × 36 = 108

a₅ = 3a₄ = 3 × 108 = 324
