Question

# Write recursive formula and explicit formula. 62,57,52,47,42,...

Hint:

- Recursive Formula is a formula that defines the each term of sequence using the previous/preceding terms.

## The correct answer is: a_n=77-15n

### Explanation:

- We have given a sequence 62,57,52,47,42,....
- We have to find the recursive and explicit formula of the given sequence.

Step 1 of 2:

We have given a sequence 62,57,52,47,42,....

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 -15

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
