Complete the series :
N3, P9, R27, T81, ________.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → V243
Each term has a letter and a number, and the two parts follow separate rules.
Letters: N, P, R, T move 2 places forward each time, so the next letter is T + 2 = V.
Numbers: 3, 9, 27, 81 are the powers of 3 (each is 3 times the one before), so the next number is \(81\times3=243\).
