किस अनुक्रम में \(d=-\frac{4}{5}\) है?
Which sequence has \(d=-\frac{4}{5}\)?
Explanation opens after your attempt
A. \(3,\frac{11}{5},\frac{7}{5},\frac{3}{5},\ldots\)
Concept
In the first option, \(\frac{11}{5}-3=-\frac{4}{5}\), and the next difference is also \(-\frac{4}{5}\). Use common denominators while subtracting fractions.
Why this answer is correct
The correct answer is A. \(3,\frac{11}{5},\frac{7}{5},\frac{3}{5},\ldots\). In the first option, \(\frac{11}{5}-3=-\frac{4}{5}\), and the next difference is also \(-\frac{4}{5}\). Use common denominators while subtracting fractions.
Exam Tip
पहले विकल्प में \(\frac{11}{5}-3=-\frac{4}{5}\) और अगला अंतर भी \(-\frac{4}{5}\) है। भिन्नों में हर समान करके घटाएं।
