Answer:
(d) 1, 4, 9, 16
Step-by-step explanation:
The terms of an arithmetic sequence will have a common difference.
The differences between terms of the sequences given are ...
(a) 2 -1 = 1, 3 -2 = 1, 4 -3 = 1 . . . . common difference of 1
(b) 4 -2 = 2, 6 -4 = 2, 8 -6 = 2 . . . . common difference of 2
(c) -2 -0 = -2, -4 -(-2) = -2, -6 -(-4) = -2 . . . . common difference of -2
(d) 4 -1 = 3, 9 -4 = 5 . . . . difference is not common
The sequence 1, 4, 9, 16 is not an arithmetic sequence.
