Chapter 2.4, Problem 17E

Find the solution to each of these recurrence relations and initial conditions. Use an iterative approach such as that used in Example 10.

   $a_n=3a_{n-1},a_0=2$

   $a_n=a_{n-1}+2,a_0=3$

   $a_n=a_{n-1}+n,a_0=1$

   $a_n=a_{n-1}+2n+3,a_0=4$

   $a_n=2a_{n-1}-1,a_0=1$

   $a_n=3a_{n-1},1a_0=1$

   $a_n=n{a}_{n-1},a_0=5$

   $a_n=2n{a}_{n-1},a_0=1$
