Frequently Asked Questions

What is an arithmetic sequence?

A sequence where each term differs by a constant (common difference). Formula: aₙ = a₁ + (n-1)d.

What is a geometric sequence?

A sequence where each term is multiplied by a constant (common ratio). Formula: aₙ = a₁ × r^(n-1).

How do I find the pattern in a sequence?

Check differences between consecutive terms for arithmetic sequences, ratios for geometric sequences, or second differences for quadratic patterns.
