Answer:

a_{n}=4+3(n-1)

Step-by-step explanation:

The given recursive rule is

a_{1}=4\\a_{n}=a_{n-1}+3

According to this recursive rule, the sequence is

4, 7, 10, 13, 16, 19,...

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

a_{n}=a_{1}+(n-1)d

Where d=3 and a_{1}=4

Replacing these values, we have

a_{n}=4+3(n-1)

Therefore, the explict form is a_{n}=4+3(n-1), which can be used to find any tem of the arithmetic sequence.

Hello.

The answer is <em>D. It is reviewed and amended.  </em>The reason why is because the State Constitution(s) are usually longer than the regular Constitution, which has roughly 4,000 words. State Constitutions are normally 8,500 words or longer. So it takes a long time to amend because they are longer.
