Answer:
3,6,9,12
Step-by-step explanation:
In geometric progression the ratio of two consecutive terms is equal. The ratio of two consecutive terms of GP is called common ratio.
So in order to check which of the sequence is geometric progression, we see in which the ratio of two consecutive terms is equal.
The common ratio of first sequence is 3.
The common ratio of second sequence is 2.
The common ratio of third sequence is 5.
The last sequence is 3,6,9,12
Let us see the common ratio.
Since, we got a different ratio. Hence, it is not a geometric sequence.
Last option is correct.
