Tofind:The explicit formula for thegiven geometric sequence.
Answer to Problem 28PPE
Thus, the recursive formula for the geometric sequence
Explanation of Solution
Given information:
The given geometric sequence is
Conceptused:
A geometric sequence is a sequence in which the ratio consecutive terms is constant.
A sequence of the form
The recursive formula for the geometric sequence is the iterative relation between consecutive terms
The given geometric sequence is
The first term of the sequence is 4and the common ratio is 2.
The nth term of sequence is
Now,
Thus, the recursive formula for the geometric sequence is
Conclusion:
Thus, the recursive formula for the geometric sequence
