Answer:
[tex]\begin{gathered} The\text{ first five terms are:} \\ 1,3,5,7\text{ and 9} \end{gathered}[/tex]
Explanation:
Here, we want to find the first five terms of the arithmetic sequence
The first term, when n = 1 will be:
[tex]a_1\text{ = 2\lparen1\rparen-1 = 1}[/tex]
The second term when n = 2, will be:
[tex]a_2\text{ = 2\lparen2\rparen-1 = 4-1 = 3}[/tex]
The third term when n = 3, will be:
[tex]a_3\text{ = 2\lparen3\rparen - 1= 6-1 = 5}[/tex]
The fourth term when n = 4 will be:
[tex]a_4\text{ = 2\lparen4\rparen - 1 = 7}[/tex]
Lastly:
The fifth term when n = 5 will be:
[tex]a_5\text{ = 2\lparen5\rparen - 1= 10-1 = 9}[/tex]
