A descending geometric sequence is a sequence in which the ratio between successive terms is a positive constant which is less than 1.
The ratio between successive numbers must be a constant.
In a sequence, the ratio of the third term to the second term is the one successive from the ratio of the second to the first. The successive ratios are : u2/u1, u3/u2, u4/u3 and so on. In a geometric sequence, these would all be the same.
No it is not.
A single number does not constitute a sequence.
The ratio is 4.
the answer is 4
Not sure about this question. But, a geometric sequence is a sequence of numbers such that the ratio of any two consecutive numbers is a constant, known as the "common ratio". A geometric sequence consists of a set of numbers of the form a, ar, ar2, ar3, ... arn, ... where r is the common ratio.
It is a sequence of numbers such that the ratio of successive terms is a constant.
A static sequence: for example a geometric sequence with common ratio = 1.
