यदि (a=5) और (d=13) है, तो \(a_7-a_2\) क्या होगा?
If (a=5) and (d=13), what will \(a_7-a_2\) be?
Explanation opens after your attempt
B. (65)
Concept
There are (5) gaps between \(a_7\) and \(a_2\), so the difference is \(5\times13=65\). For term difference, look at the difference of positions.
Why this answer is correct
The correct answer is B. (65). There are (5) gaps between \(a_7\) and \(a_2\), so the difference is \(5\times13=65\). For term difference, look at the difference of positions.
Exam Tip
\(a_7\) और \(a_2\) के बीच (5) अंतर हैं इसलिए अंतर \(5\times13=65\) है। पदों के अंतर के लिए पद-संख्या का अंतर देखें।
