RECURSION
1. Suppose $100.00 is deposited into a savings account with an interest rate of 4% compounded quarterly. How much is in the account for each of the first 8
quarters?
Because this is a discrete model, it can be modeled as a sequence. Although the menu says Recursion, it can be used for both explicit and recursive sequences.
From the Main Menu, press 8 to open the sequence editor. If the type is not an, press e(TYPE)q(an). The account pays 1% per quarter so enter the formula as
shown, using q(n) for n. Press l.
To create a table of values, press y(SET). Select Start and End values and press l after entering each value. To display the table, press d
u(TABLE).
This sequence can also be viewed as a graph. Before plotting the graph, set a window by pressing Le (V-Window). Press d. To see the graph,
press u(GPH-PLT). To trace on the graph, press Lq(Trace).
