General Forms of a Sequence

General Forms of a Sequence

 

Sequence- Is an ordered list of terms or elements.

Arithmetic Sequence- the difference between one term and the next is a constant. Also called the Common Difference.

Geometric sequence formula-  In a Geometric Sequence each term is found by multiplying the previous term by a constant. Also called the Common Ratio.

Finite sequence- Is a function with domain 1,2,3.

Infinite sequence- Is a function with domain 1,2,3,4.... etc.

Series- Is the sum of a sequence.

Explicit formula- Each domain is an answer not based on any values.

Recursive Formula- Each domain is a answer based on a previous answer.
