1) yes: 2 because if you multiply 6 by 2 you get 12 and so on. 2) 5x3=15, 15•3=45, 45•3=135, 135•3=405. 405 is the answer :)

1. The correct answer among the choices provided is the first option. It is a geometric sequence and the common ratio is 2.
2. Fifth term in the geometric sequence is 405. The pattern in this sequence is to triple the last term to get the next answer.
