Question

Whats the explicit formula sequence

Answer 1

Whats the explicit formula sequence

Answer 2

C.

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`.
