  means
  42,43,47,53,61- is to read as 41,43,47,53,61-
  
  then next number will be 61+10=71 as difference in consecutive numbers are 2,4,6,8,10..

• 42+0+0=42;
  42+1+1=43;
  43+2+2=47;
  47+3+3=53;
  53+4+4=61;
  61+5+5=71 this will be the ans.
  47+2+4=53;
  53+3+5=61;
  so apply same sequence 61+4+6=71

• the difference = 1,4,6,8 are prime numbers
  n we left 2,3,5,7 which are prime nums..
  so next unprime num after 8 is 9
  so 61+9=70

• If first number is 41
  
  => prime number sequence
  
  => next number = 67

• Ans=71.
  42 43 47 53 61 71
  1 4 6 8 10
  The difference between each nos are the table of 2.

• Ans : 71
  42 to 43 in between difference 1 and also 43 to 47 diff 4 and 47 to 53 diff 6 so next num is 71
• 11 years agoHelpfull: Yes(0) No(1)
• its 71 since diff between two consecutive nos is odd
• 11 years agoHelpfull: Yes(0) No(1)
• difference between 1,4,6,8,10
  so next number is 71
