यदि (p+2), (2p+5), (4p+1) समांतर श्रेणी के लगातार तीन पद हैं, तो (p) क्या है?
If (p+2), (2p+5), (4p+1) are three consecutive terms of an arithmetic progression, what is (p)?
Explanation opens after your attempt
A. (5)
Concept
From (2(2p+5)=(p+2)+(4p+1)), (4p+10=5p+3), so (p=7). The correct option should be (7).
Why this answer is correct
The correct answer is A. (5). From (2(2p+5)=(p+2)+(4p+1)), (4p+10=5p+3), so (p=7). The correct option should be (7).
Exam Tip
(2(2p+5)=(p+2)+(4p+1)) से (4p+10=5p+3) और (p=7) आता है। सही विकल्प (7) होना चाहिए।
