Let a_n represent the number of bacteria after \frac{n}{2} hours.

so

a_0 is the number of bacteria after 0/2 = 0 hours

a_1 is the number of bacteria after 1/2 hours

a_2 is the number of bacteria after 2/2 = 1 hours and so on


so if we list a few terms of this sequence, we have:

a_0=1

a_1=1*2

a_2=1*2*2

a_3=1*2*2*2

a_4=1*2*2*2*2


so clearly, a_n, the number of bacteria after \frac{n}{2} hours, is equal to 2^{n}.
 

 a_4_8 is the number of bacteria after
 
\frac{n}{2}=\frac{48}{2}= 24 hours.

Thus, we calculate  a_4_8, which is 2^{48}.


Answer: the number of bacteria after 24 hours is 2^{48}.
