Question
Write a recursive formula for the given sequence. 81,85,89,93,97,....
Hint:
- Recursive Formula is a formula that defines the each term of sequence using the previous/preceding terms.
The correct answer is: a_n=a_(n-1)+4.
Explanation:
- We have given a sequence 81,85,89,93,97,...
- We have to find the recursive formula.
Step 1 of 1:
We have given a sequence 81,85,89,93,97,...
The given sequence is an AP.
We know that the recursive formula for any AP is 
, where d is common difference.
Here the common difference is 4
So, The recursive formula is
