For each sequence, find a general term.

Question

For each sequence, find a general term:

1) 4/5, 5/6, 6/7, ...

2) log 10, log 100, log 1000, …

3) √2, √4, √6, √8, √18, ...

Answer 1

1) a_{n}=(n+3)/(n+4)

2) a_{n}=log(10^{n})

3) a_{n}=sqrt{2n}, herę I think that the sqrt{18} that you write is a typo. It should be sqrt{10} maybe?
