  (18,24,5)=>18+5=23+1=24
  (21,27,8)=>21+8=29-1=28
  (17,23,4)=>17+4=21+2=23
  (24,30,x)=>x=8
  24+x-2=30
  x=8

• take as triplets
  24-18=6;6-1=5
  27-21=6;6+2=8
  23-17=6;6-2=4
  30-24=6;6+3=9
  so the next no. is 9

• 24-18=6
  sum digits of last no. i.e. 2+4=6 and 6-1=5
  27-21=6
  2+7=9 and 9-1=8
  23-17=6
  2+3=5 and 5-1=4
  30-24=6
  3+0=3 and 3-1=2
  so the next term will be 2
