lk, qg, vc,___, fu
To find, the missing term = ?
The pattern follow:
The first letter is five steps forward and second letter is four steps backward.
The first letters are:
l ( + 5) → q ( + 5) → v ( + 5) → (a) ( + 5) → f
The second letters are:
k ( – 4) → g ( – 4) → c ( – 4) → (y) ( – 4) → u
The missing term = ay
Hence, the missing term is ay.
