अनुक्रम \(8,12,16,20,\ldots\) में (50) के बारे में सही कथन कौन-सा है?
Which statement about (50) is correct for the sequence \(8,12,16,20,\ldots\)?
Explanation opens after your attempt
Correct Answer
C. (50) इस अनुक्रम का पद नहीं है/(50) is not a term of this sequence
Step 1
Concept
The general term is \(a_n=4n+4\), and (4n+4=50) gives \(n=\frac{23}{2}\). If the position is not a natural number, the given number is not a term.
Step 2
Why this answer is correct
The correct answer is C. (50) इस अनुक्रम का पद नहीं है / (50) is not a term of this sequence. The general term is \(a_n=4n+4\), and (4n+4=50) gives \(n=\frac{23}{2}\). If the position is not a natural number, the given number is not a term.
Step 3
Exam Tip
सामान्य पद \(a_n=4n+4\) है और (4n+4=50) से \(n=\frac{23}{2}\) मिलता है। पद-संख्या प्राकृतिक संख्या न हो तो दिया पद अनुक्रम में नहीं होगा।
