how to find the common ratio of geometric sequence

A sequence is geometric sequence if the sequence reveals a common ratio.  To get the common ratio divide the 2nd term with the first term or  the 3rd term with the 2nd term,  ....:
Examples of sequences
1. 1, 5, 25, 125....
    5  =   5            the common the ratio is 5    indicated as     r= 5    the ratios were all checked
    1                     ( don't  jump to conclusion if  only one ratio is tested..)    

     25 = 5 
      5

      125 =5
       25

  2. 100, 50, 25, 5......
        50  =   1                r= 1
       100      2                     2

        25   =   1
        50        2

        5      =   1
       25          2  

  

In # 3 the common ratio of the geometric sequence  , r= 1/2
        
Practice Test
Find the common ratio of the following geometric sequences
1.   1, 4, 16, 64 ...
2.   1/2, 1, 2, 4,....
3.   500, 250, 125, ....
4    1/9, 1, 9, 81,...
5.  -5, 25, - 125,....
6.   1/3, 1/9, 1/27, . . .
