Parts (a), (b), (c) are solved. d,e,f,g,h,i needs to be solved

I also added all the photos.

 

(a) Given that, 

an= 6* an-1+ 7* an-2

Compare this equation with, 

an= c1 an-1 + c2* an-2

We get that, 

c1= 6 

and c2= 7

 

(b) r2-c1r-c2= 0

Put the value of c1 and c2 in the above equation, 

r2-6*r-7= 0



(c) a*r2*b*r+c= 0

a= 1

b= -6 

and c= -7

### Solving the Recurrence Relation

**Problem Statement:**
Solve the recurrence relation. Given:
- \( a_0 = 3 \)
- \( a_1 = 6 \)
- \( a_n = 6a_{n-1} + 7a_{n-2} \)

Show your work in the space provided.

**Steps:**

a. **Find \( c_1 \) and \( c_2 \):**

The recurrence relation can be expressed as:
\[ a_n = 6a_{n-1} + 7a_{n-2} \]

b. **Substitute \( c_1 \) and \( c_2 \) into the following equation:**
\[ r^2 - c_1 r - c_2 = 0 \]

- **Values to be determined:**
  - \( c_1 = \)
  - \( c_2 = \)

c. **Identify \( a \), \( b \), and \( c \) in the quadratic equation.**

- \( a = \)
- \( b = \)
- \( c = \)

d. **Use the quadratic formula to find the two roots.**

Here is the quadratic formula:
\[ \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \]

- **Solution Steps:**
  - Substitute the values of \( a \), \( b \), and \( c \) to find the roots.
  - Work to be shown in the space provided.
