Geometric Sequence

• A sequence with a constant ratio between successive terms
  • The ratio tells us how to get from one term to another
• Each term is found by multiplying the previous term by a constant
• It's called a geometric series because it is like increasing dimensions in geometry

Formula

• $ar^{n - 1}$
  • $a$ is the first term
  • $r$ is the common ratio
  • $n$ is the term you are looking for
