Rigoberto Pittman · Answer 1

It is the first choice.

Step-by-step explanation:

This is a sequence where

the next term is obtained by adding 6.

first term = - 9 + 6 (0) = - 9

second term = - 9 + 6 (1) = - 3

third term = - 9 + 6 (2) = 3

4th term = - 9 + 6 (3) = 9

and 81 = - 9 + (6*15).

So the answer is Sigma (-9 + 6n) from n = 0 to n = 15.
