यदि (x-1,2x+3,4x+1) समान अंतर वाले अनुक्रम के लगातार तीन पद हैं तो (x) का मान क्या है?
If (x-1,2x+3,4x+1) are three consecutive terms of a sequence with equal differences, what is the value of (x)?
Explanation opens after your attempt
B. (6)
Concept
Equal differences give (2x+3-(x-1)=4x+1-(2x+3)). This gives (x=6).
Why this answer is correct
The correct answer is B. (6). Equal differences give (2x+3-(x-1)=4x+1-(2x+3)). This gives (x=6).
Exam Tip
बराबर अंतर से (2x+3-(x-1)=4x+1-(2x+3)) मिलता है। इससे (x=6) आता है।
