Solve the problem.Suppose that certain bacteria can double their size and divide every 30 minutes. Write a recursive sequence that describes this growth where each value of n represents a 30-minute interval. Let a1 = 451 represent the initial number of bacteria present.
A. a1 = 451; an = 
an-1 for n > 1.
B. a1 = 451; an = 2 an-1 for n > 1.
C. a1 = 451; an = 2 an+1 for n > 1.
D. an = 2 a1 for all values of n.
