1) Examining common differences(d):
2 , 5 , 8 , 11
d 1 = 5 - 2 = 3
d 2 = 8 - 5 = 3
d 3 = 11 - 8 = 3
Since d 1 = d 2 = d 3 = 3 , a constant difference is maintained throughout the sequence.
The common difference: d = 3
2) Testing for common ratio(r)
r 1 = 5 2 = 2.5
r 2 = 8 5 = 1.6
r 3 = 11 8 = 1.375
Since r 1 r 2 r 3 , the sequence has no common ratio.
