Write a recursive formula for finding the [tex]n[/tex]th term of the arithmetic sequence:
[tex]15.75, 14.25, 12.75, \ldots[/tex]
A. [tex]a_1 = 15.75, \, a_n = a_{n-1} + 1.5[/tex]
B. [tex]a_1 = 12.75, \, a_n = a_{n-1} - 1.5[/tex]
C. [tex]a_1 = 11.25, \, a_n = a_{n-1} + 1.5[/tex]
D. [tex]a_1 = 15.75, \, a_n = a_{n-1} - 1.5[/tex]
