From your textbook, or from other sources, learn what is a geometric progression and what is its common ratio.

Then solve the problem and answer the questions on your own.


One good source to learn this subject is the group of lessons
    - Geometric progressions
    - The proofs of the formulas for geometric progressions
    - Problems on geometric progressions
    - Word problems on geometric progressions
in this site.

Also,  you have this free of charge online textbook in ALGEBRA-II in this site
    - ALGEBRA-II - YOUR ONLINE TEXTBOOK.

The referred lessons are the part of this online textbook under the topic
