In the given question, a letter-number series is given with one or more terms missing as shown by (?). Choose the missing term out of the given alternatives.
A196, I169, P144, V121, A100, ...?...
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → E81
Each term has a letter and a number, and the two parts follow separate rules.
Letters (by position in the alphabet): A(1) → I(9) → P(16) → V(22) → A, moving forward by 8, 7, 6 and 5. After Z the count goes on from A (22 + 5 = 27 = 26 + 1, that is, A). The next step is 4: A + 4 = E
Numbers: 196, 169, 144, 121, 100 are \(14^{2},13^{2},12^{2},11^{2},10^{2}\), so the next is \(9^{2}=\) 81
