Answer:
1.) Common Difference = 1/2
2.) Common Ratio = 1/3
Step-by-step explanation:
The formula to identify whether it is a Geometric sequence or an Arithmetic sequence is by using their formula: Geometric sequence ( a2÷a1) and multiplying the common ratio to first (a1 x r) until it finishes the given sequence. Arithmetic sequence ( a2-a1) and adding the common difference to first (a1 + d).
