Answer:
C.
Step-by-step explanation:
According to the problem, the first term is 7 and the reason is 13.
This is a geometric sequence, which general term is defined as
[tex]a_{n}=a_{1}r^{n-1}[/tex]
So, replacing given values, we have
[tex]a_{n}=7(13)^{n-1}[/tex]
Therefore, the right answer is C., because it shows the same form as the one we found. That specific rule is to find a general term [tex]n[/tex].
