Question Analysis
This question involves identifying whether a given sequence is an arithmetic sequence. The main focus is on checking if there is a constant difference between consecutive terms.

Key Concept Explanation
An arithmetic sequence is a sequence of numbers where the difference between consecutive terms is constant. This constant difference is called the common difference, usually denoted by d.

Step-by-Step Solution
To determine if 5, 9, 13, 17, ... is an arithmetic sequence, we calculate the difference between each pair of consecutive terms:
9 − 5 = 4
13 − 9 = 4
17 − 13 = 4
Since the difference between consecutive terms is always 4 (...
