समांतर श्रेणी \(17,22,27,32,\ldots\) का (25)वाँ पद क्या है?
What is the (25)th term of the arithmetic progression \(17,22,27,32,\ldots\)?
Explanation opens after your attempt
B. (137)
Concept
Here (a=17) and (d=5), so (a_{25}=17+24(5)=137). Use (a_n=a+(n-1)d) even for larger terms.
Why this answer is correct
The correct answer is B. (137). Here (a=17) and (d=5), so (a_{25}=17+24(5)=137). Use (a_n=a+(n-1)d) even for larger terms.
Exam Tip
यहाँ (a=17) और (d=5), इसलिए (a_{25}=17+24(5)=137)। बड़े पद के लिए भी (a_n=a+(n-1)d) लगाएं।
