Frequently Asked Questions
What is the difference between arithmetic and geometric sequences?
An arithmetic sequence adds a constant difference between terms; a geometric sequence multiplies by a constant ratio between terms.
How do I find the sum of the sequence?
For arithmetic: sum = n/2 × (first term + nth term). For geometric: sum = first term × (1 − ratio^n) / (1 − ratio), when ratio ≠ 1.
