D. \(a_1=6, a_{n+1}=a_n+3n+2\)

Step 1

Concept

The additions are (5,8,11), so (3n+2) is added. Exam tip: match both the first term and changing additions.

Step 2

Why this answer is correct

The correct answer is D. \(a_1=6, a_{n+1}=a_n+3n+2\). The additions are (5,8,11), so (3n+2) is added. Exam tip: match both the first term and changing additions.

जोड़ (5,8,11) हैं इसलिए (3n+2) जुड़ता है। पहला पद और बदलते जोड़ दोनों मिलाएँ।
