Which of the following is not a geometric sequence? 2 You're right! You've correctly selected the sequence that is not geometric. From among a set of options, the student was able to select the non-geometric sequence. The student was able to do this even though some of the sequences contain fractions and negative terms. 1 Sorry, that's not right. The sequence ... is geometric. Since each term is equal to negative one-half times the previous term, this is a geometric sequence with a common ratio of -1/2. The student was not able to select a non-geometric sequence from among a set of options. Some of these sequences include fractions and negative terms; this may or may not be the source of the difficulty. 3 Sorry, that's not right. The sequence ... is geometric. Since each term is equal to three halves times the previous term, this is a geometric sequence with a common ratio of 3/2. The student was not able to select a non-geometric sequence from among a set of options. Some of these sequences include fractions and negative terms; this may or may not be the source of the difficulty. 4 Sorry, that's not right. The sequence ... is geometric.
