Geometric Series

• A geometric sequence is a sequence where each term is calculated by multiplying the constant in the previous term.
• The constant between any two consecutive terms is always equal called common ratio (r).
• Geometric Sequence: Sum of n Term Formula: Sn = a1 (1 - rn) / 1 - r

  where:

  • Sn = the sum of the first n terms
  • a1 = the first term
  • n = the number of terms
  • r = the common ratio
• Geometric Sequence: Sum of n Term Formula: Sn = a1 (1 - rn) / 1 - r

  where:

  • Sn = the sum of the first n terms
  • a1 = the first term
  • n = the number of terms
  • r = the common ratio
