Step 1:
Arithmetic sequence
In an Arithmetic Sequence the difference between one term and the next is a constant.
Geometric sequence
Geometric Sequences. In a Geometric Sequence each term is found by multiplying the previous term by a constant.
Step 2
The sequence is 3 , 5 , 7
[tex]\begin{gathered} \text{Common difference = 2nd term - 1st term or 3rd term - 2nd term} \\ \text{= 5 - 3 = 2} \\ =\text{ 7 - 5 = 2} \end{gathered}[/tex]Final answer
Since the common difference is constant, the sequence is Arithmetic sequence.
