Question

A sequence is defined as follows: \( a_1 = 1, a_2 = 2 \), and \( a_n = a_{n-1} + a_{n-2} \) for \( n \geq 3 \). What is the 6th term of the sequence?

• A. 5
• B. 8
• C. 13
• D. 21

Hint:

For recursive sequences, compute each term iteratively using the given relation and initial conditions. Double-check the term number.
