Question

Identify the sequence below as arithmetic, geometric, or neither. Then find the next two terms a5 and a6

10, 30, 90, 270,

Answer 1

Geometric sequence of common ratio = 3

a5 would be: 810,

and a6 = 2430

Explanation:

The sequence is a geometric sequence because each term is produced by multiplying the previous one by the factor 3 (called the common ratio)

then terms a5 and a6 would be: 810, and 2430 respectively
