A scientist observes a culture of bacteria. Initially (at day 0), there are \(u_0=5\) bacteria. Each day, the number of bacteria doubles. Let \(u_n\) be the number of bacteria at day \(n\).
Part A: Define the Sequence Recursively
  • The initial term is \(u_0 =\)
  • The recursive rule is \(u_{n+1} =\)
    \(\times u_n \).
Part B: Calculate the Terms for the First Five Days
  • \(u_1 =\)
    bacteria
  • \(u_2 =\)
    bacteria
  • \(u_3 =\)
    bacteria
  • \(u_4 =\)
    bacteria
  • \(u_5 =\)
    bacteria
