Chapter 8.2, Problem 55E

To determine

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

Answer to Problem 55E

First ten terms of the arithmetic sequence are $1.55,1.6,1.65,1.7,1.75,1.8,1.85,1.9,1.95,2$ respectively.

Explanation of Solution

Given information:

Given arithmetic sequence

  $a_n=1.5+0.05n$

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	$1.55$
2	$1.6$
3	$1.65$
4	$1.7$
5	$1.75$
6	$1.8$
7	$1.85$
8	$1.9$
9	$1.95$
10	$2$

Hence,first ten terms of the given arithmetic sequence are $1.55,1.6,1.65,1.7,1.75,1.8,1.85,1.9,1.95,2$ respectively.
