Chapter 8.2, Problem 51E

To determine

To find: the first 10 terms of the given arithmetic sequence using graphing utility.

Answer to Problem 51E

First ten terms of the arithmetic sequence are $-1,3,7,11,15,19,23,27,31,35$ respectively.

Explanation of Solution

Given information:

Given arithmetic sequence

  $a_n=4n-5$

Calculation:

Use the table feature of graphing utility to find the first 10 terms of the arithmetic sequence by using following steps:

Press MODE key, select Seq in the fourth line and hit Enter

  

Press $Y=$ and Enter the sequence,

  

Set the table by pressing TBLSET and then press TABLE,

$n$	$a_n$
1	$-1$
2	$3$
3	$7$
4	$11$
5	$15$
6	$19$
7	$23$
8	$27$
9	$31$
10	$35$

Hence,first ten terms of the given arithmetic sequence are $-1,3,7,11,15,19,23,27,31,35$ respectively.
