• Everyone says 59 and that's fine.
  
  But what about this:
  
  2 * 3 = 6
  13 * 28 = 364

• 2+3=5,inorder to get 6,1 should be added
  2+3+6=11,inorder to get 13,2 should be added
  2+3+6+13=24,inorder to get 24,4 should be added
  2+3+6+13+28=51,hence 8 should added
  1,2,4,8......is added
  59 is the answer.....
