The arithmetic sequence is given with the first term (which is a) as 29, and the common difference (which is d) as 8, that is
d=37-29
d=45-37
d=8
The explicit formular is now derived as follows;
[tex]\begin{gathered} a_n=a+d(n-1) \\ a_n=29+8(n-1) \\ a_n=29+8n-8 \\ a_n=21+8n \end{gathered}[/tex]The explicit formular is shown as
nth term = 21 + 8n
