It is hard to tell sometimes, but an arithmetic sequence would have the same number added or subtracted. That doesn't seem to be the case.
A could way to check for a geometric sequence is to divide the first number by the second. I divided 3888 by 216 and got 18.
Next try to divide to 216 by 18 to see if the answer is 12.
Finally divide 12 by 18 to see if the answer is 2/3.
If they work out, then you have a geometric sequence.
Identify the sequence...
3,888, 216, 12, 2/3...
a. arithmetic
b. geometric
c. neither
d. both
Is it c or d?
