[Week 2]- Geometric Series

What I have learned:

- The sum of n terms of a geometric series
- Use a rule to determine the sum of n terms of a geometric series, then solve related problems.
- Use a rule to determine the nth term in a geometric sequence.
- Use a rule to determine any of n, t1, tn, or r in a geometric sequence.
- Use a rule to determine n and Sn in geometric series, given the values of r, n, or Sn.

Ex. Find the S15 of the sequence -5, 10, -20…

Ex. Find the n of the sequence 1-2+4-8+…-512
