  coz total no of terms iz 7 then suppose 36 54 18 we take 18*2=36 and 18*3=54/ same u check 18 27 9 again we gaet same ....then finally we 9 18.5 4.5 actual value 9 z ri8 but 1.5 iz wrong coz of 4.5*3=13.5 correct ans iz 13.5

• 18*3=54
  18*2=36
  similarly
  4.5*3=13.5
  4.5*2=9
  ans=18.5

• First of all the question should be like this -> Find the odd one out ,Now if that's the case then
  36 = 18 x 2
  54 = 18 x 3
  18 = 9 x 2
  27 = 9 x 3
  same as,
  9 = 4.5 x 2
  now
  18.5 ≠ 4.5 x 3
  therefore this is odd one AND the answer is option (B) i.e. 18.5
