It is an arithmetic sequence (with constant difference 0), or a geometric sequence (with constant ratio 1).

An arithmetic sequence.
The constant increment.
No, the Fibonacci sequence is not an arithmetic because the difference between consecutive terms is not constant
Arithmetic Sequence
To verify that a given sequence is an arithmetic progression (AP) using the paper cutting and pasting method, arrange the numbers in a line in increasing order. Cut the numbers along the baseline and shift them so their ends align in a straight line. If the gaps between the aligned numbers are consistent throughout the sequence, then it is an AP. If the gaps vary, then the sequence is not an AP.
7
An arithmetic sequence.
It is an arithmetic sequence if you can establish that the difference between any term in the sequence and the one before it has a constant value.
The constant increment.
No, the Fibonacci sequence is not an arithmetic because the difference between consecutive terms is not constant
Arithmetic 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.

It is an ordered set of numbers in which the difference between any member of the sequence (except the first) and its predecessor is a constant.
It is a sequence of numbers such that the ratio of successive terms is a constant.
