Evaluating sequences in recursive form

The  exercise appears under the Algebra I Math Mission. This exercise practices evaluating sequences in recursive form.

Types of Problems
There is one type of problem in this exercise:
 * 1) Generate the first four terms of the sequence.: This problem has a function that describes a sequence and user is asked to generate the first four terms of the sequence.

Strategies
Knowledge of systems of equations are highly recommended to ensure success in this exercise.
 * 1) To generate any term in a sequence that is defined recursively, we can use the value of the term, or terms, that are explicitly given by this definition, and evaluate successive terms using the recursive rule.

Real-life Applications

 * 1) Problems like this will appear on standardized tests, like the SATs and the ACTs.
