The nth term of the series

Question

5/2,20/13,10/9,20/23.....

Answer 1

First of all , a series would be the sum of the terms of a sequence, you show
a sequence.

That is quite an obscure sequence, I had to resort to Wolfram to find a pattern, it showed it as
term(n) = 20/(5n+3)

What methods have you learned that would let you find that ?
