Concept explainers
To find: Whether the sequence is arithmetic, geometric or neither, find the common difference or common ratio and also find the sum of the first fifty terms if the sequence is arithmetic or geometric.
Answer to Problem 69AYU
The sequence is neither arithmetic nor geometric.
Explanation of Solution
Given information:
The series is
Calculation:
Calculate nth term.
Calculate
Calculate the difference of nth term and
Since the difference of consecutive terms is not a constant, the sequence is not arithmetic.
Calculate the common ratio of nth and the
Since the common ratio is not a constant term the sequence is not a geometric sequence.
Therefore, the sequence is neither arithmetic nor geometric.
