A. 5
B. 1
C. 6
D. 3
🧠 Explanation:
Given series = 3, 9, 25, 49, 81, 121
Second term = 9 = 3²
Third term = 25 = 5²
Fourth term = 49 = 7²
Fifth term = 81 = 9²
Sixth term = 121 = 11²
So from 2nd term onward pattern is perfect squares of odd numbers
First term = 3
Nearest square = 2² = 4
So we write first term as 2² − x = 3
⇒ 4 − x = 3
⇒ x = 1
Final Answer = 1
