• 11 years agoHelpfull: Yes(12) No(13)
• (6,11),(17,22),(8,x)
  11-6 = 5
  22-17 = 5
  8-x = 5
  so x = 3
• 11 years agoHelpfull: Yes(2) No(24)
• 11-6=5,22-17,13-8=5
  hence 13
• 11 years agoHelpfull: Yes(2) No(0)
• 11-6=5
  22-7=5
  8-x=5
  so,x=13
  
• 11 years agoHelpfull: Yes(1) No(0)
• 11-6=5
  22-17=5;
  so
  x-8=5
  gives x=13

• ans : 30
  6+11=17
  22+8=30 ans
• 11 years agoHelpfull: Yes(1) No(0)
• 17+5=22
  11-3=8
  6+1=7
  alternatively adding and subtracting odd numbers in decreasing order.

• 25
  alternating series
  hence 13,17,19,15
  now 13+6=19, 17-2=15
  19+6=25
• 11 years agoHelpfull: Yes(0) No(3)
• 6*2-1==11
  6*3-1=17
  6*4-2=22
  
  6+2=8
  
  8*2-1=15
  8*3-1=23
  8*4-2=30
  
  hence the series is 6,11,17,22,8,15,23,30 so on
  So ans is 15
