• each number wil be obtained by adding the prime no. to the previous..
  10+2=12
  12+3=15
  15+5=20
  20+7=27
  27+11=38
  ans.is 38
• 14 years agoHelpfull: Yes(3) No(0)
• 4) 38 ..... Difference of nos. are consecutive primes
• 14 years agoHelpfull: Yes(2) No(0)
• 38
• 14 years agoHelpfull: Yes(1) No(3)
• Ans 5)39
  
  the terms increasing in prime no sequence
  like 2,3,5,7,
  and next term will increase 11
  so ans is 5)39
• 14 years agoHelpfull: Yes(1) No(9)
• 2) THAT IS 38
• 14 years agoHelpfull: Yes(1) No(0)
• 27+11 ( next prime number ) =38
• 14 years agoHelpfull: Yes(1) No(0)
• 10+2=12
  12+3=15
  15+5=20
  20+7=27
  ;
  all prime numbers in ascending order are added
  so next is 27+11=38
• 14 years agoHelpfull: Yes(1) No(0)
• addition of prime numbers
  10 (+2),12(+3),15(+5),20(+7),27(+11)=> solution is 38
  
  option (4)
• 14 years agoHelpfull: Yes(1) No(0)
• The answer is 38 because it is a sequence of the addition of prime numbers
  10+2=12
  12+3=15
  15+5=20
  20+7=27
  27+11=38
• 14 years agoHelpfull: Yes(1) No(0)
• 4)38
• 14 years agoHelpfull: Yes(1) No(0)
• 38 is the answer.
  The Sequence is adding consecutive primr numbers
• 14 years agoHelpfull: Yes(1) No(0)
• 38...
  add prime numbers respectively
• 14 years agoHelpfull: Yes(0) No(1)
• option4
  the next no is 38
• 14 years agoHelpfull: Yes(0) No(0)
• 4) 38 ... difference btw nos are consecutive primes
• 14 years agoHelpfull: Yes(0) No(0)
• 10+2=12, 12+3=15, 15+5=20, 20+7=27,
  That is adding next prime numbers to previous digit.
  Therefore Next would be 27 + 11= 38
