A Geometric Sequence is the ratios of consecutive terms that are the same.
the number r is the common ratios of the sequence.
The difference between an Arithmaic Sequence and Geometric Sequence
Arithmatic Geometric
Geometric
The sequence whose nth term is 2^n is geometric. For this seqence, the common ratio between consecutive terms is 2.
2,4,8,16...2^n...
4/2= 2
The sum of Geometric Sequences
if r is less that absolute value 1 then the equation is s=a1/1-r
