A geometric series.
To check whether it is an arithmetic sequence, verify whether the difference between two consecutive numbers is always the same.To check whether it is a geometric sequence, verify whether the ratio between two consecutive numbers is always the same.

what is the recursive formula for this geometric sequence?
The definition is, as given in the question, a sequence where the difference between any pair of consecutive terms is the same,.
Ratio
It is a constant, other than 0 or 1.
A geometric series.
The sequence 2, 3, 5, 8, 12 is neither arithmetic nor geometric. In an arithmetic sequence, the difference between consecutive terms is constant, while in a geometric sequence, the ratio between consecutive terms is constant. In this sequence, there is no constant difference or ratio between consecutive terms, so it does not fit the criteria for either type of sequence.
A descending geometric sequence is a sequence in which the ratio between successive terms is a positive constant which is less than 1.
A geometric sequence is an ordered set of numbers such that (after the first number) the ratio between any number and its predecessor is a constant.
No, the Fibonacci sequence is not an arithmetic because the difference between consecutive terms is not constant
Arithmetic Sequence
The ratio between successive numbers must be a constant.
To check whether it is an arithmetic sequence, verify whether the difference between two consecutive numbers is always the same.To check whether it is a geometric sequence, verify whether the ratio between two consecutive numbers is always the same.
