Q:
# what are the first four terms of the geometric sequence an=2 an-1 and a1=3β

Accepted Solution

A:

Answer:3, 6, 12, 24Step-by-step explanation:This is a recursive formula which allows the next term in a sequence to be found from the previous term in the sequenceGiven[tex]a_{n}[/tex] = 2[tex]a_{n-1}[/tex] with aβ = 3, thenaβ = 2 Γ aβ = 2 Γ 3 = 6aβ = 2 Γ aβ = 2 Γ 6 = 12aβ = 2 Γ aβ = 2 Γ 12 = 24Thus the first 4 terms are 3, 6, 12, 24
