Which of the following options will replace the question mark (?) in the given series?
Z1, x2, V3, T4, ?
Show answer & explanation
Correct answer: A
Explanation
Series: Z1, X2, V3, T4, ?
Analyze the letter pattern
The letters are: Z, X, V, T, ?
Z → X → V → T
In the alphabet: Z (26), X (24), V (22), T (20)
The pattern is: moving backward by 2 letters each time.
After T (20), moving back 2 letters gives R (18).
Analyze the number pattern
The numbers are: 1, 2, 3, 4, ?
This is a simple sequence increasing by 1 each time.
After 4 comes 5.
So, the missing term is R5.
Hence, the correct answer is option (1).
