What is the common ratio for the following sequence 12 -14 18 -116?

To find the common ratio of a geometric sequence, we divide each term by its preceding term. However, the sequence provided (12, -14, 18, -116) does not exhibit a consistent ratio, as the ratios between consecutive terms are -14/12, 18/-14, and -116/18, which are not equal. Therefore, this sequence is not geometric and does not have a common ratio.


What is descending geometric sequence?

A geometric sequence is a sequence where each term is a constant multiple of the preceding term. This constant multiplying factor is called the common ratio and may have any real value. If the common ratio is greater than 0 but less than 1 then this produces a descending geometric sequence. EXAMPLE : Consider the sequence : 12, 6, 3, 1.5, 0.75, 0.375,...... Each term is half the preceding term. The common ratio is therefore ½ The sequence can be written 12, 12(½), 12(½)2, 12(½)3, 12(½)4, 12(½)5,.....


What is the 12th term of a geometric sequence in which the common ratio is 2 and the first term is 12?

Is 3 6 12 24 48 an arithmetic sequence?

No, geometric, common ratio 2


Is geometric sequence a sequence in which each successive terms of the sequence are in equal ratio?

Yes, that's what a geometric sequence is about.


What is the common ratio sequence of 3?

A common ratio sequence, or geometric sequence, is defined by multiplying each term by a fixed number, known as the common ratio. If the first term of the sequence is 3 and the common ratio is, for example, 2, the sequence would be 3, 6, 12, 24, and so on. If the common ratio were instead 1/2, the sequence would be 3, 1.5, 0.75, 0.375, etc. Essentially, the sequence can vary widely based on the chosen common ratio.


What is the common ratio in this sequence 6 12 24 48 96?

The common ratio is 2.


Which explains why the sequence 216 12 23 is arithmetic or geometric?

The sequence 216 12 23 is neither arithmetic nor geometric.


What is the common ratio in the sequence 12 -18 27?

12 × ratio = -18 → ratio = -18/12 = -3/2 = -1.5 Checking: -18 × ratio = -18 × -3/2 = 27 as required The common ratio is -3/2 (or -1.5)


What is the common ratio of 3 6 12 and 24?

Because 3 * 2 = 6, 6 * 2 = 12, and 12 * 2 = 24, the common ration of the sequence is 2. If we are given the fact that the sequence does have a common ratio, the answer can be found by simply taking 6/3 = 2.


If the sum of an infinite geometric series is 12 and the common ratio is one third then term 1 is what?
