Its like we are adding 5 to all the odd position terms and multiplying by 2 all the even even terms.
Like:
0 is at position 1, means its an odd position => add 5
5 is at position 2, means its an even position => multiply number at this position by 2, and so on..

Therefore, the series is like:
0 , 0+5 , 5*2 , 10+5 , 15*2 , 30+5, 35*2 , 70+5 , 75*2, ...

So, next term is 150.
