Sequence Calculator

Enter the first few terms of a number sequence (comma-separated). The calculator will detect if it is arithmetic, geometric, or Fibonacci-like, show the next 5 terms, and give the nth term formula.

Sequence Terms (comma-separated, at least 3)

Sequence Types

Arithmetic: Constant difference between terms. Formula: aₙ = a₁ + (n−1)d

Geometric: Constant ratio between terms. Formula: aₙ = a₁ × r^(n−1)

Fibonacci-like: Each term = sum of the two preceding terms.
