Question

Complete the following series by replacing the ?: (TBLD, VEPI, XHTN, ?)

• A. ZJVP
• B. ZVJP
• C. ZKXS
• D. ZKXP

Hint:

Convert each letter to its position number (A=1...Z=26) and track how much each of the four positions increases from term to term.

Answer 1

The Correct Option is C

A quicker way is to work through the increment pattern position by position and eliminate wrong options as we go, instead of computing every letter's numeric value together at once.

1. Look at the first letters across the three given terms: T, V, X, which are positions 20, 22, 24. Each jumps by 2, so the next first letter should be 24 + 2 = 26, which is Z. Every option starts with Z, so this does not eliminate anything yet, but it confirms Z is correct.
2. Look at the second letters: B, E, H, which are positions 2, 5, 8. Each jumps by 3, so the next should be 8 + 3 = 11, which is K. This eliminates option (1) ZJVP, since it has J instead of K.
3. Look at the third letters: L, P, T, which are positions 12, 16, 20. Each jumps by 4, so the next should be 20 + 4 = 24, which is X. This eliminates option (2) ZVJP, since its letters do not follow this pattern.
4. Look at the fourth letters: D, I, N, which are positions 4, 9, 14. Each jumps by 5, so the next should be 14 + 5 = 19, which is S. This eliminates option (4) ZKXP, since it ends in P instead of S.
5. Only option (3), ZKXS, satisfies all four positional patterns together: Z, K, X and S.

So the missing term in the series is ZKXS, confirming option (3) as the correct answer.
