## Example Questions

### Example Question #31 : Building Functions

Write an explicit recursive function that describes the following sequence.

**Possible Answers:**

**Correct answer:**

This question is testing one's ability to identify and understand an arithmetic sequence and create the recursive function. Recall that for a function to be recursive, it depends on the previous term in the sequence. It is also important to recall that the difference in an arithmetic sequence is just a constant.

For the purpose of Common Core Standards, writing arithmetic and geometric recursive and explicit sequences, falls within the Cluster A of build a function that models a relationship between two quantities concept (CCSS.Math.content.HSF.BF.A).

Knowing the standard and the concept for which it relates to, we can now do the step-by-step process to solve the problem in question.

Step 1: Identify the arithmetic difference of the sequence.

Step 2: Identify the basic form for an arithmetic recursive sequence.

where

Step 3: Substitute known values into the form from Step 2.

Following the steps from above for this particular problem is as follows.

Step 1: Identify the arithmetic difference of the sequence.

Step 2: Identify the basic form for an arithmetic recursive sequence.

where

Step 3: Substitute known values into the form from Step 2.
