Which explicit rule is correct for the sequence \(12,19,26,33,\ldots\)?
Explanation opens after your attempt
A. \(a_n=7n+5\)
Concept
The difference is (7), and at (n=1) the value must be (12), so \(a_n=7n+5\). In exams, take the difference as the coefficient of (n).
Why this answer is correct
The correct answer is A. \(a_n=7n+5\). The difference is (7), and at (n=1) the value must be (12), so \(a_n=7n+5\). In exams, take the difference as the coefficient of (n).
Exam Tip
अंतर (7) है और (n=1) पर मान (12) चाहिए, इसलिए \(a_n=7n+5\) है। परीक्षा में अंतर को (n) का गुणांक मानें।
