The sequence below shows the number of bacteria Arjun observed each hour for a science experiment: 5, 20, 80, 320,1,280,...
Which recursive function describes the number of bacteria observed at the nth hour?
f(1) = 5
f(n + 1) = 4f(n)
f(1) = 1
f(n+1) = 4f(n)
f(1) = 1
f(n+1) = 5f(n)
f(1) = 5
f(n+1) = 2f(n) + 10
