(a)
Answer to Problem 40CR
Theninth term of the sequence is
Explanation of Solution
Given:
The third term is
Calculation:
Use T183 calculator to find the ninth term of the sequence.
The first step is to press the 2nd and STAT button to access the list menu. Highlight the OPS column and then press 5.
The display is shown in Figure 1
Figure 1
The second step is to write the sequence followed by the variable name and then the corresponding limits and then press the enter button as shown in Figure 2
