यदि समानांतर श्रेढ़ी में \(a_5=28\) और (d=4) है, तो \(a_2\) क्या होगा?

If an arithmetic progression has \(a_5=28\) and (d=4), what is \(a_2\)?

Correct Answer

B. (16)

Step 1

Concept

From \(a_5\) to \(a_2\), move back three gaps, so (a_2=28-3(4)=16). When moving backward, subtract the common difference.

Step 2

Why this answer is correct

The correct answer is B. (16). From \(a_5\) to \(a_2\), move back three gaps, so (a_2=28-3(4)=16). When moving backward, subtract the common difference.

Step 3

Exam Tip

\(a_5\) से \(a_2\) तक तीन अंतर पीछे जाना है, इसलिए (a_2=28-3(4)=16)। पीछे जाते समय समान अंतर घटाएं।
