Geometric Sequence

• Formula for the geomrtric sequence/progression in n-th term (an): an = a1 * rn−1

  where:

  • an = the n-th term
  • a1 = the first term
  • n = the term number
  • r = the common ratio
• • an = the n-th term
  • a1 = the first term
  • n = the term number
  • r = the common ratio
