Write the first five terms of the following sequences and obtain the corresponding series
(i) ` a_(1) = 7 , a_(n) = 2a_(n-1) + 3 "for n" gt 1`
(ii)` a_(1) = 2, a_(n) = (a_(n-1))/(n+1) "for n" ge 2 `

Explanation

Let's solve the given sequences step by step.

### Part (i)

We are given:
- \( a_1 = 7 \)
- \( a_n = 2a_{n-1} + 3 \) for \( n > 1 \)
