  5 + 5 = 10
  10 + 6 = 16

• Ans is 40.
  
  10-1 = 9;
  16-5 = 11,
  23-10=13,
  31-16 = 15,
  then,
  x-23 = 17.
  
  so x=40.

• ans=10diff betwn 2 successive terms is(4,5,6,7,8,9)
• 10 years agoHelpfull: Yes(0) No(0)
• ans is 386
  first no + last no=1+7,get a middle no=8
  If we add 3+6=9(386)
• 7 years agoHelpfull: Yes(0) No(0)
• 187=7+1=8
  264=2+4=6
  473=4+3=7
