Each rule represents a geometric sequence. If the given rule is recursive, write it as an explicit rule. If the rule is explicit, write it as
a recursive rule. Assume that f(1) is the first term of the sequence.
2. f(n) = 11(2)"-1
3. f(1) = 2.5; f(n) = f(n-1) • 3.5 for n 22
4. f(1) = 27; f(n) = f(n-1).
for n 22
5. f(n) = 4(0.5)"-1
