यदि \(a_1=3\) और (d=8) है, तो \(a_{14}-a_5\) का मान क्या है?
If \(a_1=3\) and (d=8), what is the value of \(a_{14}-a_5\)?
Explanation opens after your attempt
B. (72)
Concept
There are (9) gaps between \(a_{14}\) and \(a_5\), so the difference is \(9\times8=72\). Term differences can be found directly using (d).
Why this answer is correct
The correct answer is B. (72). There are (9) gaps between \(a_{14}\) and \(a_5\), so the difference is \(9\times8=72\). Term differences can be found directly using (d).
Exam Tip
\(a_{14}\) और \(a_5\) के बीच (9) अंतर हैं, इसलिए अंतर \(9\times8=72\) है। पदों का अंतर सीधे (d) से निकाला जा सकता है।
