Find the common difference by subtracting successive terms.
\The common difference is 2 factors.
\Add 10 to last term of the sequence to get the next termin the sequence.
\Continue adding 12, and 14 untill the next three terms are found.
\20 + 10 = 30, 30 + 12 = 42 and 42 + 14 = 56.![\"\"](\"http://www.mathskey.com/userfiles/image/steps_images/solution.JPG\")
The next three terms are 30, 42, 56.
