Find the common difference by subtracting successive terms.
\The common difference is +9.
\Add 9 to last term of the sequence to get the next termin the sequence.
\Continue adding 9 untill the next three terms are found.
\–29 + 9 = –20, –20 + 9 = –11, and –11 + 9 = –2.![\"\"](\"http://www.mathskey.com/userfiles/image/steps_images/solution.JPG\")
The next three terms are –20, –11, –2.
