125,25,5,1... , ...every next one is divided by  , so ratio is
nth of General Term of a Geometric Sequence: 
where  is the first term of the sequence and  is the common ratio.
We have the common ratio  and  ,then
so, check sixth term above using this formula:
 which is
Find the nth term of the geometric sequence
7,49,343,2401,...
it is a "geometric sequence" which that means that each successive term is multiplied by the same factor, and in this sequence the common factor is 
Geometric sequences have an nth term of the form  where is the first term,  is the common factor and  is the number of the term (nth term).
