Write a recursive rule for the sequence an=-4+4n

and

Step-by-step explanation:

The sequence is given by .

Now, putting n = 1, .

Now, putting n = 2,

Therefore, .........(1)

Again, putting n = 3,

Therefore, .......... (2)

Hence, from equations (1) and (2), we can write

and

So, this above relation gives the recursive rule for the given sequence. (Answer)
