Saving and Sharing Apps
This section contains step-by-step instructions for creating, saving, and sharing an App called Fibonacci that is based on the Sequence
App.
Press Apps, highlight the Sequence App, and press the RESET menu key to clear this App of
data. Press the OK menu key to complete the reset and then press the START menu key.
1. The Sequence App starts in the Symbolic view, with ten sequence definitions. The Fibonacci
Sequence definition is:
• U1(1)=1
• U1(2)=1
• U1(N)=U1(N-2)+U1(N- 1 )
Enter this definition of U1 as shown in the figure to the right.
Tip: use the menu keys to enter (N-2), (N- 1 ), etc.
2. Press the Num key to see a table of values for the sequence. You can explore the sequences
using the direction keys. With the highlight bar in the N column, you can also manually
enter any counting number and the table will jump to that value.
