What is the next 3 terms of the geometric sequence 6,4,6,9,13.5

Question

Really not understanding how my teacher got the anwser. Need help.

Answer 1

This is not a geometric sequence. Is it possible that the sequence is just 4,6,9,13.5?

 

If so you would find the next terms by multiplying the previous term by the common ratio which in this case is 1.5.

 

If the sequence does in fact start with the 4 the next three terms would be 20.25,30.375,45.5625
