Question

A sequence can be generated by using an = 6a(n-1), where a₁ = 8 and n is a whole number

greater than 1. What are the first four terms in the sequence?
F 8, 16, 24, 32
G 8, 14, 20, 26
H 8,48,384, 18432
J 8,48, 288, 1728

Answer 1

J

Explanation:

to obtain a term in the sequence multiply the previous term by 6

a₁ = 8

a₂ = 6 × a₁ = 6 × 8 = 48

a₃ = 6 × a₂ = 6 × 48 = 288

a₄ = 6 × a₃ = 6 × 288 = 1728

the first 4 terms are 8, 48, 288, 1728
