किसी अनुक्रम में \(w_1=0\) और \(w_n=w_{n-1}+2^{n-1}\) है। \(w_5\) का मान क्या होगा?
In a sequence, \(w_1=0\) and \(w_n=w_{n-1}+2^{n-1}\). What is the value of \(w_5\)?
Explanation opens after your attempt
B. तीस(30)
Concept
\(w_5=0+2+4+8+16=30\). In exams, apply the exponent (n-1) correctly.
Why this answer is correct
The correct answer is B. तीस / (30). \(w_5=0+2+4+8+16=30\). In exams, apply the exponent (n-1) correctly.
Exam Tip
\(w_5=0+2+4+8+16=30\) है। परीक्षा में घात (n-1) को सही लगाएँ।
