10,5,13,10,16,20,19,?

• there 2 alternative series...
  first one is 10,13,16,19... in which next-term=current-term+3
  second one is 5,10,20... in which next-term=2*current-term
  so the answer is 2*20=40....

• the answer will be be 40.
  as odd number places is incremented by 3 i.e next term will be previou+3.
  even number place is multiple of 2 i.e next term is previous*2.

  & 5,10,20,....so 40,80...like tht hence ans is 40

• odd place numbers 10,13,16,19 here the difference are 3
  Even place numbers 5,10(5*2),20(5*4) so the next number will be 30(5*6)
  here 2,4,6 are the positioning numbers of 10,20,30 from 5.
  So the answer is 10,5,13,10,16,20,19,30,22......
