Correct Answer

B. (107)

The correct answer is B. (107). For \(a_{12}\), (9) is added (11) times, so \(a_{12}=107\). Exam tip: the rule is applied one less time than the term number.

Step 3

Exam Tip

\(a_{12}\) के लिए (9) को (11) बार जोड़ा जाता है इसलिए \(a_{12}=107\) है। पद संख्या से एक कम बार नियम लगता है।
