This site contains an online calculator allowing users to find the nth term of an arithmetic, geometric, or the Fibonacci sequence. The calculator will also display the sum of the first n terms as well as a short sequence segment.
The major goal is to provide users with an online calculator for finding the n-th term of an arithmetic, geometric, or the Fibonacci sequence as well as the sum of the first n terms.
Target Student Population:
Calculus II students.
Prerequisite Knowledge or Skills:
Calculus of sequences and series.
Content Quality
Rating:
Strengths:
This site contains an online calculator allows users to find the nth term of an arithmetic, geometric, or the Fibonacci sequence. The calculator will also display the sum of the first n terms as well as a short sequence segment. For arithmetic and geometric sequences, users can input the starting number, the common difference value, and whether the sequence should be increasing or decreasing. The site also contains a section giving basic definitions of sequence and series under consideration.
Concerns:
Users can input only integer or decimal values that puts certain limitations of the generated series.
Potential Effectiveness as a Teaching Tool
Rating:
Strengths:
The site contains a brief summary of what a sequence is, what arithmetic and geometric sequences are, and how terms may be calculated that is a big plus if the module is used as a part of self-guided study. Users are also provided with a code for embedding this calculator in a website or LMS.
Concerns:
Although the reading material does discuss how the n-th terms of geometric and arithmetic sequences can be calculated, some users might benefit from being able to see this calculation for their input examples.
Ease of Use for Both Students and Faculty
Rating:
Strengths:
This site is very easy to use. The layout is nice and clear.
Concerns:
The ad in the middle of the page (between the calculator and the reading material) is a bit distracting.
