Thank you for the opportunity to help you with your question!

LET n be the position of a number in the series

If n is odd

rule is 

N = No +15*(n-1)

N= 30 + 15*(n-1

IF n IS EVEN THEN

the rule is 

N = 5* n


the fith number will thus be

N = 30+ 15(5-1)

= 30 +60

= 90

the sixth number will be

N= 5*n

= 5*6

=30

Please let me know if you need any clarification. I'm always happy to answer your questions.
