arithmetic sequence
The common difference is the difference between two numbers in an arithmetic sequence.
A single term, such as 51474339 does not define a sequence.
You subtract any two adjacent numbers in the sequence. For example, in the sequence (1, 4, 7, 10, ...), you can subtract 4 - 1, or 7 - 4, or 10 - 7; in any case you will get 3, which is the common difference.
could also be negative
The sequence is neither arithmetic nor geometric.

A single term, such as 51474339 does not define a sequence.
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.
It is the "common difference".It is the "common difference".It is the "common difference".It is the "common difference".
Since there are no graphs following, the answer is none of them.
yes. A zero common difference represents a constant sequence.
You subtract any two adjacent numbers in the sequence. For example, in the sequence (1, 4, 7, 10, ...), you can subtract 4 - 1, or 7 - 4, or 10 - 7; in any case you will get 3, which is the common difference.
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.
