The sequence given is:
−24,−12,0
To check if a sequence is a geometric sequence we calculate the common ratio r (which is a constant ratio maintained throughout the sequence).
r is obtained by dividing a term by its preceding term:
1) r 1 = - 12 - 24 = 1 2
2) r 2 = 0 - 12 = 0
Clearly, 1 2 0
For this sequence the ratios r 1 r 2 so the sequence is not a geometric sequence.
