What is the ninth term of a geometric sequence if the third term is 36 and the fourth term is 72? 144 108 4608 2304 4 Correct, good job! The student correctly determined the 9th term of a geometric sequence. 1 Sorry, that's not right. The question is asking for the 9th term, not the 5th term. The student gave the next term in a geometric sequence, instead of the 9th term. 2 Sorry, that's not right. Perhaps you added the third and fourth terms, but this is not the correct rule to generate successive terms in the sequence. This is a geometric sequence, which means there is a common ratio between terms. For example, the sequence 2, 4, 8, 16, 32,... has a common ratio of two. To generate the next term in this sequence, you multiply the current term by two. The student added two terms of the sequence together. 3 That's incorrect, but you are close! It looks like you found the 10th term, instead of the 9th term. Student gave the 10th term. ExtendGeometric
