Alphabet series puzzle with positional increments: complete the pattern SCD, TEF, UGH, ____, WKL by analyzing letter-wise progressions and consistent offsets

Given data

• Series: SCD, TEF, UGH, ?, WKL.

Concept/Approach (why this method)

Handle each position independently. Look for constant alphabetical increments (A=1, B=2, …, Z=26) across first, second, and third letters.

Step-by-Step calculation
1) First letters: S(19), T(20), U(21), ?, W(23) ⇒ +1 each step ⇒ missing is V(22).2) Second letters: C(3), E(5), G(7), ?, K(11) ⇒ +2 each ⇒ missing is I(9).3) Third letters: D(4), F(6), H(8), ?, L(12) ⇒ +2 each ⇒ missing is J(10).4) Combine: V + I + J ⇒ VIJ.

Verification/Alternative

Check neighbors: UGH → VIJ (U→V +1, G→I +2, H→J +2); VIJ → WKL (V→W +1, I→K +2, J→L +2) — pattern holds.

Common pitfalls

• Applying a single uniform step to all positions; here the first letter uses +1 while the other two use +2.

Final Answer
VIJ
