Letter pair series ZA YB XC WD – UGC NET Question

In this pattern, the first letters go backward in the alphabet: Z(26), Y(25), X(24), W(23), decreasing by 1. The second letters go forward: A(1), B(2), C(3), D(4), increasing by 1. The next first letter is V(22), and the next second letter is E(5), forming VE. Therefore VE is the unique pair that preserves both movements.

Option A:
Option A, UF, uses U as the first letter, which is 2 steps before W instead of 1. It also advances the second letter to F, which is 2 steps beyond D. These larger jumps break the consistent step of 1 in both directions, making UF incorrect.

Option B:
Option B, WD, simply repeats the last term of the series. The sequence is clearly moving and does not indicate any repetition pattern. Thus WD cannot serve as the next term.

Option C:
Option C is correct because V and E are exactly one step beyond W backward and D forward respectively. It keeps the first letter moving towards the beginning of the alphabet and the second letter moving towards the end. This symmetry ensures VE follows the established rule.

Option D:
Option D, VG, uses the correct first letter V but sends the second letter to G, two steps ahead of E. That distorts the +1 progression in the second position. As a result, VG does not properly continue the series.
