Writing Expressions from a table or for a sequence

In class students learned how to write a variable expression for a sequence.  An example provided below:




                                                                           5, 8, 11, 14.....3n + 2

In the expression above (3n +2) the variable, n, represents the term number so the first term (n = 1) can be found by substituting 1 in for n in the expression   3(1)+2 = 5.   Finding the expression that represents the sequence makes it easy to find any term in the sequence.  So if we wanted to find the the 100th term (n = 100) in the sequence we would substitute 100 in for the n in the expressions  3(100) +2 = 302.

The homework is listed below and the class notes are attached.
