Acertain arithmetic sequence has the following explicit formula for the nth term: an = 4 + (n - 1)(7) the same sequence has the following recursive formula: an = an-1 + what number belongs in the blank space in the recursive formula?

Step-by-step explanation:

We know that the nth term in Arithmetic sequence is given by :-

..................(1)

Given: A certain arithmetic sequence has the following explicit formula for the nth term:

.............................(2)

When we compare (1) and (2), we get

Also, the recursive formula in A.P. can be written as

Therefore, The same sequence has the following recursive formula:

step-by-step explanation:

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.
