You minus 3. 8 minus 3 is 5, 5 minus 3 is 2 = 8, 5, 2
arithmetic sequence
The common difference is the difference between two numbers in an arithmetic sequence.
The sequence is neither arithmetic nor geometric.
The difference between succeeding terms in a sequence is called the common difference in an arithmetic sequence, and the common ratio in a geometric sequence.

An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms is constant. For example, the sequence 2, 5, 8, 11, 14 has a common difference of 3. Another example is 10, 7, 4, 1, which has a common difference of -3. In general, an arithmetic sequence can be expressed as (a_n = a_1 + (n-1)d), where (a_1) is the first term and (d) is the common difference.
yes. A zero common difference represents a constant sequence.
An excellent example of an arithmetic sequence would be: 1, 5, 9, 13, 17, in which the numbers are going up by four, thus having a common difference of four. This fulfills the requirements of an arithmetic sequence - it must have a common difference between all numbers.
It is the difference between a term (other than the second) and its predecessor.

An arithmetic sequence.
Common difference, in the context of arithmetic sequences is the difference between one element of the sequence and the element before it.
