Concept explainers
To explain whether sequence is arithmetic geometric or neither.
Answer to Problem 7.31EP
Sequence is not arithmetic and not geometric.
Explanation of Solution
Given information:
The sequence
Formula used:
d is common difference of the arithmetic sequence
r is common ratio of geometric sequence
Calculation:
The sequence
.
.
And so on.
Check for arithmetic sequence
Using common difference formula
Common difference is for first two terms
On solving,
Common difference for second and third term
On solving,
As shown above common difference of all the term is not same
Sequence is not arithmetic
Check for geometric
Using common ratio formula
Common ratio for first two terms
On solving,
Common ratio for second and third terms
On solving,
As shown above common ratio of the terms is not same
Then, sequence is not geometric
Hence, sequence is not arithmetic and not geometric.
