Answer :
Common difference is 6.
Further explanation:
Let us define common difference and common ratio first.
Common Difference: Common difference is the difference between two consecutive terms of an arithmetic sequence.
Common Ratio: The ratio between two consecutive terms of a geometric sequence is called common ratio.
Given sequence is:
30,24, 18, 12, 6, ...
Common difference:
[tex]30-24 = 6\\24 - 18 = 6\\18-12=6[/tex]
Common difference is 6.
As the common difference is same, the given sequence is an arithmetic sequence. So, it will have common difference not common ratio.
