Given:
The arithmetic sequence is,
[tex]-9,-2,5,12,...[/tex]To find:
The first term.
Explanation:
We know that,
If the arithmetic sequence is given,
[tex]a_1,a_2,a_3,.....[/tex]Then the first term is,
[tex]a=a_1[/tex]The common difference is,
[tex]d=a_2-a_1[/tex]Comparing we get,
The first term is a = -9.
Final answer:
The first term is -9.
