Each of the following sums is the beginning of an arithmetic series. Find the

*n*^{th}term of each series, for the specified value of*n*. Homework Help ✎(−2) + (−5) + (−8) + ...,

*n*= 129 + 15 + 21 + ...,

*n*= 20

How is this sequence progressing?

How can you use that to determine what the 12th term will be?
