For example in the arithmetic sequence 3, 9, 15, 21, 27, the common difference is 6. An arithmetic sequence can be known as an arithmetic progression. The difference between consecutive terms is an arithmetic sequence is always the same.
(b) 3, 6, 9, 12, 15, . . . (a) This sequence is a list of even numbers, so the next three numbers will be 12, 14, 16. (b) This sequence is made up of the multiples of 3, so the next three numbers will be 18, 21, 24.
The common difference d is,d=15–9=21–15=6.
