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

 first is geometric   3*(5)^n-1 (power is n-1 that is 5 to the power n-1)

second is arithmetic  14+(n-1)*2


please put n instead of n-1 if you consider numbering from 0.

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