Explanation opens after your attempt
B. (6)
Concept
\(a_6=a_1+5d\), so (47=17+5d) and (d=6). Count the number of gaps between the two terms.
Why this answer is correct
The correct answer is B. (6). \(a_6=a_1+5d\), so (47=17+5d) and (d=6). Count the number of gaps between the two terms.
Exam Tip
\(a_6=a_1+5d\), इसलिए (47=17+5d) और (d=6)। दो पदों के बीच अंतरालों की संख्या गिनें।
