Letter series AZC BYD CXE DWF – UGC NET Question

Each term follows a clear rule: the first letter increases by 1 (A, B, C, D, …), the second letter decreases by 1 from the end (Z, Y, X, W, …) and the third letter increases by 1 from C onward (C, D, E, F, …). After DWF, the first letter should become E, the second V and the third G. Therefore EVG is the only option that satisfies all three simultaneous movements.

Option A:
Option A, EVF, gives the correct first letter E and second letter V but keeps the third letter at F. The third letter must also advance by one position compared to the previous term’s third letter F. Since EVF does not reflect this change, it fails to meet the full pattern.

Option B:
Option B is correct because its letters E, V and G correspond precisely to the next steps in their respective progressions. It advances the first and third letters by one and moves the second letter back by one, exactly as earlier terms did. This complete alignment makes EVG the accurate continuation of the series.

Option C:
Option C, EWG, changes the second letter from W instead of V, skipping the required step in the second position. It also disrupts the relationship between the second and third letters across terms. Because it ignores the careful backward stepping of the middle letter, EWG is not consistent.

Option D:
Option D, FVG, advances the first letter by two positions from D to F while using the correct second and third letters. This breaks the +1 rule for the first position. Thus, even though part of the term looks plausible, the entire group fails the strict pattern.
