Question
Write recursive formula and explicit formula. -4, 5,14,23,32,...
The correct answer is: a_n=9n-13.
Step 1 of 2:
We have given a sequence -4,5,14,23,32,...
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 9
So, The recursive formula is
Step 2 of 2:
The given sequence is an AP.
So, The explicit formula will be
.
Step 2 of 2:
The given sequence is an AP.
So, The explicit formula will be
.
