Arithmetic, Geometric & Fibonacci Sequences

Sequence Generator Guide

Supported Sequences

  • Arithmetic: a(n) = a₁ + (n-1)d, sum S = n(2a₁+(n-1)d)/2
  • Geometric: a(n) = a₁ × q^(n-1), sum S = a₁(1-q^n)/(1-q)
  • Fibonacci: F(n) = F(n-1) + F(n-2)
  • Custom Recurrence: define recurrence with a formula

Tips

  • Generate up to 1000 terms
  • In custom formula, a, b, c represent the last 3 terms
  • Supports copy as comma-separated or CSV format
  • All calculations done locally in your browser
