Q184
ReasoningAnalogy, Classification & Odd One Out
Which would come in place of '?' in the given series? ACE, FGH, ?, PON
  1. a.KKK
  2. b.JKI
  3. c.HJH
  4. d.IKL

Answer: (A) KKK

Pattern: ACE (positions 1,3,5; +5=K), FGH (positions 6,7,8; the gaps decrease), ? should be KKK (positions 11,11,11), PON (positions 16,15,14). Looking at the letter-step pattern: A+5=F+5=K+5=P; C+4=G+4=K+4=O; E+3=H+3=K+3=N. So the third term has K,K,K = KKK.
