Step 1 To Determine: Given sequence is geometric or not. 2, 1, 12, 14,  Step 2 Explanation: When given sequence is geometric, it is must have common ratio. Common ratio is a ratio just divide each number from the number preceding it in the sequence. In given sequence, ratio of 1 & 2 is: 12=12
ratio of 1/2 & 1 is:
121=12
ratio of 14& 12 is:
1412=24=12 We see that, all ratio are same So, common ratio : r=12 It means given sequence is geometric sequence
