For the sequence, write an explicit formula for the nth term.
1/5, 2/7, 3/9, 4/11...
I don't know how to start. I have other sequences also, so I need to learn, not just get the answer. Thank You

top is just 1,2,3,4, ...n
top = n
bottom would be 2 n but have to start with 5 when n = 1 and 2n=2 so
bottom = (3+2n)
so
An = n/(3+2n)
top = n
bottom would be 2 n but have to start with 5 when n = 1 and 2n=2 so
bottom = (3+2n)
so
An = n/(3+2n)
