Recursive formula= a(n)=a(1)(n-1)+d
a(n)= 9(n-1)+2
explicit formula= a(n)= a(1)+(n-1)d
a(n)= 9+(n-1)2
12th row= a(12)=9+(12-1)2
a(12)=9+11(2)
a(12)=9+22
a(12)=31
4 1/2
Try Cymath it’s great for this stuff
Answer:
Recursive
Explicit
Step-by-step explanation:
An arithmetic sequence an be represented by a recursive rule which gives the first term and defines the nth term by relating it to the previous term, or by an explicit rule which defines the nth term as a function of n.
The recursive rule is that we have the initial term. To find the subsequent term, we will take that <em>previous term</em> and add it to our common difference.
Hence, we are <em>relating the previous terms</em> to define the nth term.
For the explicit rule, we simply have a function of n. To find the nth term, we can substitute our desired term n for n and evaluate.
Answer:
these are quadratic graphs
Step-by-step explanation:
The correct answer for this item and the other way to write this rule is through this:
(x , y) -> (x - 8 , y + 4)
According to the rule T - 8, 4(x,y) , a triangle on a coordinate plane is translated that is why we end up getting the answer shown above.
