Question

Can you show me how to solve this?

**Problem 4: Find \( a_3 \), \( a_4 \), and \( a_5 \) of the sequences.**

**a. Given:**

- \( a_1 = 1 \)
- \( a_2 = 2 \)
- Recursive formula: \( a_n = 2a_{n-1} + 3a_{n-2} \)

**b. Sequence formula:**

- General term: 
  \[
  a_n = (n+1) + (n+2) + (n+3) + \cdots + (3n)
  \] 

(Note: For part (b), the summation starts at \( n+1 \) and ends at \( 3n \).)
