Arecursive rule for an arithmetic sequence is a1=4; an=an−1+3 . what is an explicit rule for this sequence? enter your answer in the box. an=

Step-by-step explanation:

The given recursive rule is

According to this recursive rule, the sequence is

Because, the recursive rule states that each new term must be 3 units greater.

Now, an explicit form of this sequence could be found using this formula

Where and

Replacing these values, we have

Therefore, the explict form is , which can be used to find any tem of the arithmetic sequence.
