Letter series BY CX DW EV – UGC NET Question

In this pattern, the first letters are B(2), C(3), D(4) and E(5), increasing by 1 each time. The second letters are Y(25), X(24), W(23) and V(22), decreasing by 1 each time. The next first letter after E is F and the next second letter before V is U. Therefore FU is the only pair that continues both the forward and backward one-step movements.

Option A:
Option A, FT, gives the correct first letter F but takes T as the second letter, which is two steps before V instead of one. This breaks the strict decrement of one in the second-letter positions. As a result, FT does not follow the series rule.

Option B:
Option B, FU, is correct because it takes F as the next first letter and U as the next second letter, maintaining a one-step change in each direction. It keeps the symmetry of moving forward by one and backward by one in the two positions. This exact mirroring is what defines the series.

Option C:
Option C, GU, changes the first letter too far ahead to G rather than F, while keeping U as the second letter. This leads to a jump of two steps in the first position instead of one. The unequal step sizes mean GU does not preserve the consistent structure of the series.

Option D:
Option D, FV, keeps the second letter V unchanged, failing to move it backward at all. The second letter must continue to step down one position at each term. By freezing the second letter, FV violates a key element of the pattern.
