1. Identify if the sequence has a common difference or a common ratio.
Common difference: subtract each term from the next term:
There is not a common difference.
Common ratio: Divide each term into the previous term:
The common ratio is 1/3; it is a geometric sequence.
2. Use the next fromula to write the formula to find the nth term in the sequence:
Evaluare the formula above for n=10 to find the 10th term:
Then, the 10th term is 1/729
