Sequence and Series Concepts in One Map
A sequence is an ordered list of numbers, and a series is the sum of its terms. Most courses split the topic into arithmetic sequences, where each term adds a fixed common difference, and geometric sequences, where each term multiplies by a fixed common ratio. Both lead to formulas for the nth term and for the sum of the first n terms.
- Arithmetic sequences: constant difference between consecutive terms
- Geometric sequences: constant ratio between consecutive terms
- Nth term: formulas that find any term directly
- Sums of series: formulas for adding the first n terms
- Convergence: when an infinite geometric series has a finite sum
Use the map to revise each formula and check when it applies. To build a map from your own lecture notes, use CogniGuide's AI generator.

Sequence and Series Questions
Common questions from students revising the topic.
What is the difference between a sequence and a series?
A sequence is an ordered list of numbers, such as 2, 4, 6, 8. A series is the sum of those terms, such as 2 + 4 + 6 + 8. The sequence lists the values, and the series adds them.
When does an infinite geometric series have a sum?
An infinite geometric series has a finite sum only when the absolute value of the common ratio is less than 1. In that case the sum equals the first term divided by one minus the ratio.
Which files can I use to make my map?
You can upload a PDF, Word or PowerPoint file, a text or Markdown file, or an image of your notes. You can also type the topic directly.
Is it free to create a sequence and series map?
Yes. The free plan allows 5 creations a week with no payment needed. Paid plans raise these limits.
