                    Lesson 1

                                                                                                                                                                          

                                                             Problem:                   Find the third term of the sequence: an = 6n- 13

                                                             Solution                    (n) is a natural number; replace (n) with the number of the term

                           Step 1:  

                     

                                                                                Solution                          a3 = 6 x 3 13

 Step 2:                        

 

                                                            Solution                          a3 = 5

                                                             Step 3:

                                                              

 Solution                    The answer is:  a3 = 5

 Step 4:                                                                      

 Complete                                                                   

                                                                                  

                                             

                                                             Try two practice problems:  

 

                                                                                               Solve the following:

 

A.

Find the tenth term of the sequence: an=15n-25

B.

Write the first three terms of the sequence: an=8n-6
