Letter series AZ BY CX DW – UGC NET Question

In this series, the first letters move forward in the alphabet (A, B, C, D, …) while the second letters move backward from the end (Z, Y, X, W, …). The next first letter after D is E and the next second letter before W is V. Combining these gives the pair EV as the unique continuation that preserves both movements simultaneously. Therefore EV correctly continues the established pattern of opposite-direction shifts in the two positions.

Option A:
Option A is correct because its first letter E follows D and its second letter V precedes W, fitting the consistent forward–backward pattern. It respects the equal step size of one position for both directions of movement. No other option maintains this exact mirror-type structure on both letters at the same time. Thus EV is the only pair that logically continues the series.

Option B:
Option B, EU, keeps the first letter E correct but changes the second letter to U, which skips one extra position from W. This breaks the consistent one-step backward movement in the second letter (Z, Y, X, W, V). Because of this extra jump, EU does not fit the precise mirror pattern. Hence, it cannot be the correct continuation.

Option C:
Option C, FW, advances the first letter too far to F and freezes the second letter at W. The first letter should only move from D to E, not to F, and the second letter should continue decreasing instead of remaining the same. This double violation means FW fails to respect both directional rules of the series.

Option D:
Option D, GV, moves the first letter forward by three positions from D to G instead of by a single step. While the second letter V is what we expect, the incorrect jump in the first letter destroys the symmetry of the pattern. Because series questions require strict consistency, GV cannot be accepted as the next term.
