What is the (n)th term of the arithmetic progression \(22,29,36,43,\ldots\)?
Explanation opens after your attempt
B. \(a_n=7n+15\)
Concept
The first term is (22) and (d=7), so (a_n=22+(n-1)7=7n+15). Remember (n-1) while forming the general term.
Why this answer is correct
The correct answer is B. \(a_n=7n+15\). The first term is (22) and (d=7), so (a_n=22+(n-1)7=7n+15). Remember (n-1) while forming the general term.
Exam Tip
पहला पद (22) और (d=7) है इसलिए (a_n=22+(n-1)7=7n+15)। सामान्य पद बनाते समय (n-1) का ध्यान रखें।
