Step 2

Why this answer is correct

The correct answer is A. (34-6n). The first term is (28) and the difference is (-6), so (a_n=28+(n-1)(-6)=34-6n). Pay attention to the sign in a decreasing sequence.

Step 3

Exam Tip

पहला पद (28) और अंतर (-6) है, इसलिए (a_n=28+(n-1)(-6)=34-6n)। घटती श्रेढ़ी में चिह्न पर ध्यान दें।
