Word series FAN GAN HAN IAN – UGC NET Question

In this series, the last two letters “AN” remain constant, while the first letter advances alphabetically. The first letters are F, G, H and I, so the next first letter should be J. Combining J with the fixed ending “AN” gives JAN. Thus JAN is the only option that maintains the simple first-letter progression.

Option A:
Option A, KAN, uses K as the first letter, which would come after J. This skips the immediate successor required by the pattern. Since the series moves one letter at a time, KAN cannot be the next term.

Option B:
Option B, IAN, repeats the last given word instead of introducing a new one. There is no indication that the pattern cycles or repeats elements. Therefore IAN is not a valid continuation here.

Option C:
Option C, GAN, is a previous term in the series. Reusing an earlier word breaks the forward movement of the first letter. Because the pattern shows steady progression, GAN cannot be the correct answer.

Option D:
Option D is correct because it uses J, the next letter after I, and keeps “AN” unchanged. It fits perfectly with the rule that only the initial letter changes step by step. Hence JAN logically completes the series.
