In an arithmetic sequence common difference will be constant. Common difference is the difference of next term to it's previous term. Like

common difference: d = Second term - first term.

Similarly in geometric sequence common ratio will be constant.

Common ratio = Second term / first term.

I have attached the table of correct match pair.

Hope this helps you!
