Find the common difference by subtracting successive terms.
\The common difference is 6.
\Add 6 to last term of the sequence to get the next termin the sequence.
\Continue adding 6 untill the next three terms are found.
\36 + 6 = 42, 42 + 6 = 48 and 48 + 6 = 54.![\"\"](\"http://www.mathskey.com/userfiles/image/steps_images/solution.JPG\")
The next three terms are 42, 48, 54.
