Determine whether the sequence

Answer to Problem 49PPS
The sequence is arithmetic.
Explanation of Solution
Given:
The sequence:
Concept Used:
A sequence is a set of numbers, called terms, arranged in some particular order.
An arithmetic sequence is a sequence with the difference between two consecutive terms constant. The difference is called the common difference.
A geometric sequence is a sequence with the ratio between two consecutive terms constant.
Calculation:
First Term:
Common Difference for Arithmetic sequence:
The common differences are constant, so the sequence is arithmetic.
Common Ratio for Geometric sequence:
The common ratios are not constant, so the sequence is not geometric.
Thus, the sequence is arithmetic.
