The first term is (15) and the difference is (-4), so (a_n=15+(n-1)(-4)=19-4n). Pay attention to the sign in a decreasing sequence.

Step 2

Why this answer is correct

The correct answer is A. (19-4n). The first term is (15) and the difference is (-4), so (a_n=15+(n-1)(-4)=19-4n). Pay attention to the sign in a decreasing sequence.

Step 3

Exam Tip

पहला पद (15) और अंतर (-4) है, इसलिए (a_n=15+(n-1)(-4)=19-4n)। घटती श्रेढ़ी में चिह्न पर ध्यान दें।
