The common difference is 6; each number after the first equals the previous number minus 6.
The common difference is the difference between two numbers in an arithmetic 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.
It appears to be -6

The common difference is the difference between two numbers in an arithmetic sequence.
common difference is the difference in every two consecutive numbers in the sequence .. or in the other way around, its the number added to a number that resulted to the next number of the sequence ..
The sequence is neither arithmetic nor geometric.
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.
