समानांतर श्रेढ़ी \(27,30,33,36,\ldots\) का सामान्य पद कौन-सा है?
What is the general term of the arithmetic progression \(27,30,33,36,\ldots\)?
Explanation opens after your attempt
A. \(a_n=3n+24\)
Concept
The first term is (27) and (d=3), so (a_n=27+(n-1)3=3n+24). Put (n=1) to check an option.
Why this answer is correct
The correct answer is A. \(a_n=3n+24\). The first term is (27) and (d=3), so (a_n=27+(n-1)3=3n+24). Put (n=1) to check an option.
Exam Tip
पहला पद (27) और (d=3) है इसलिए (a_n=27+(n-1)3=3n+24)। विकल्प की जांच के लिए (n=1) रखें।
