Question

Whats the explicit formula sequence

Answer 1

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

$a_{n}=a_{1}r^{n-1}$

So, replacing given values, we have

$a_{n}=7(13)^{n-1}$

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 $n$.
