Find the solution to each of these recurrence relations with the given intial conditions. Use an iterative approach.
c) \(a_{n} = a_{n-1} - n, a_{0} = 4\)
d) \(2a_{n-1} - 3, a_{0} = -1\)
e) \(a_{n} = (n+1)a_{n-1}, a_{0} = 2\)
f) \(a_{n} = 2na_{n-1}, a_{0} = 3\)
g) \(a_{n} = -a_{n-1} + n -1, a_{0}=7\)
