Hi,

geometric sequence  -8, 4, -2,...

Finding  the 7th term by listing out the first terms of the sequence:

  -8, 4, -2, 1, -1/2, 1/4, -1/8, ...

using a formula for finding the nth term of a geometric sequence

 where r is the common ratio.  In this ex: r = (-1/2)

 



geometric sequence  3, 6, 12, ...

Finding  the 10th term by listing out the first ten terms of the sequence:

3, 6, 12, 24, 48, 96, 192, 384, 768, 1536

using a formula for finding the nth term of a geometric sequence

 where r is the common ratio.  In this ex: r = 2
