Which of the following options will replace the question mark (?) in the given series? z1, y4, x9, w16, ?
Show answer & explanation
Correct answer: A
Explanation
Given Series: Z1, Y4, X9, W16, ?
Analyze the letter pattern:
The letters are: Z, Y, X, W, ?
In the alphabet: Z = 26, Y = 25, X = 24, W = 23
Position decreases by -1 each time: 26 → 25 → 24 → 23 → 22
The 22nd letter in the alphabet is V.
Analyze the number pattern:
The numbers are: 1, 4, 9, 16, ?
Numbers are squares of continuous numbers starting from 1: 1 → 4 → 9 → 16 → 25
Next number is square of 5 i.e., 25.
So, the next term is V25.
Hence, the correct answer is option (1).
