Question Analysis
This question involves identifying whether a sequence of perfect squares is an arithmetic sequence. The main focus is on checking for a constant difference between consecutive terms.

Key Concept Explanation
An arithmetic sequence requires a constant difference between consecutive terms. Sequences where the difference between terms changes (like those involving squares, cubes, etc., of consecutive numbers) are not arithmetic.

Step-by-Step Solution
Calculate the differences between consecutive terms in 1, 4, 9, 16, ...:
4 − 1 = 3
9 − 4 = 5
16 − 9 = 7
The differences are 3, 5, 7, which are not constant. Hence, the...
