hey sorry I need a free point !
The given series is

Where the first term, a , is 3.
And the difference is constant, that is

So the constant difference, d is 3.
Since the difference is constant, so the given series is arthmetic.
And for explicit rule, we use the formula of nth term, which is

Substituting the values of a and d, we will get

Recursive rule is used to tell us the relationship between previous and current term. And the required rule is

Answer:
-26 is the y-intercept
Step-by-step explanation:
since you already have the slope solved, you just have to plug in one of the two coordinate pairs. i plugged it (4,6) since it didnt have any negatives to work with. 6 should be where y is and 4 is x. you now should solve it as a normal equation. it gave me -26.
keep your denominator the samem...ithink
