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

  • arnāˆ’1ar^{n - 1}
    • aa is the first term
    • rr is the common ratio
    • nn is the term you are looking for
