• i'm pretty sure that this is an out-of-context question.
  this question refers to the following series: 7 3 P N 4 2 6 3 1 M L B T 4 5 G A C D F J K 1 9 8 2.......... as per this series, the answer would be (4)AF9 because in the rest of the options the individual characters have a gap, in the sequence, of two characters. in AF9: AF = 2 characters, F9 = 3 ch.

• 7 3 P N 4 2 6 3 1 M L B T 4 5 G A C D F J K 1 9 8 2......... wat is this series actually cant get yu SUNNY SAURAV.. Explain clearly

• Ans is (5)TDG
  Because, TDG=20+4+7=31 is a prime number
  Other’s sum is non prime number

• 1. GDK = 7+4+11=11 (G is 7th letter, D is 4th letter & K is 11th letter in english alphabet)
  2. 7N6 = 7+14+6=27
  3. B5C = (2+3)=5 so this option has its own calculation
  4. AF9 = 1+6+9 = 16
  5. TGD = 20+7+4 = 31
  All the sums are in odd except 4th option so Answer is 4. AF9 or the other way rest all option are similar with one another, gdk is similar to tgd, 7n6 is similar to b5c, odd is af9 with no similarity.

• This question is related to this sequence:- 73PN42631MLBT45GACDFJK1982.
  There is a gap of two letter or digits between GDK, 7N6 B5C and TGD but same gap is not there for AF9 and that makes him odd from the others.
