Answer: 3n+1
(no need to type in the "a_n" or "an" part, as it's already done)
--------------------------------------------------------------------------
Explanation:
The first term is a1 = 4 since it is given to us
The common difference is d = 3. This is the value that we add to each term to get the next as the recursive steps shows when we write a(n) = a(n-1)+3
In other words,
nth term = [ (n-1)st term ] + 3
next term = (previous term) + 3
Using a1 = 4 and d = 3, we get the following
an = a1+d(n-1)
an = 4 + 3(n-1)
an = 4+3n-3
an = 3n + (4-3)
an = 3n+1

(c)Using Linear Approximation,L(4.2)=137.6
Using Quadratic Approximation,
Step-by-step explanation:
Given:
(a)Linear Approximation,
(b)Quadratic Approximation,
(c)To approximate:
L(x)=48x-64
L(4.2)=48(4.2)-64=137.6
Also, Using Quadratic Approximation
