Select the term that can replace the question mark (?) in the following series.

ACE , GIJ , LPO , PXT , ?

Series: ACE , GIJ , LPO , PXT , ?

​Logic: each letter in the terms ACE, GIJ, LPO, and PXT follows an incremental pattern in positions with the first letters increasing by 6, 5, and 4 respectively, the second letters increasing by 6, 7, and 8 respectively, and the third letters increasing consistently by 5, leading to the next term in the series

First Letters:

A +6 =   G +5=  L +4=  P 

Next letter: P + 3 = S (19th letter)

Second Letters:

C +6 =I +7 =  P +8=  X 

Next letter: X + 9 = G (7th letter, wrapping around the alphabet)

Third Letters:

E +5= J+5= O +5 =  T 

Next letter: T + 5 = Y (25th letter)

SGY is the correct answer 

Thus, correct answer is (a) SGY
