Step-by-step explanation:
1- not a function; 3 in the domain is repeated
2- a function
3- a function
4- a function
From the recursive rule

it follows that


and so on. Notice how the subscript on a on the right side and the coefficient multiplied by 13 add up to n (n - 2 + 2 = n; n - 3 + 3 = n; and so on). If we continue the pattern, we'll end up with

so that the explicit rule for the n-th term in the sequence is

Let's solve for x.

Step 1: Add -5y to both sides.

Step 2: Divide both sides by 3.
