• 18-24=-6
  24-5=19
  21-27=-6
  27-8=19
  ...
  24-30=-6
  30-x=19
  x=11

• 7
  as becoz after every even two multiples of three the privious multicand is used as
  3*6=18
  3*8=24
  as both multiples are even we use the multipllicand of the previous one that is 5.
  and for odd multiples we use the next evn multiplicand
