    A_n = \frac{2^n}{n!}

    Let n = {1,2,3,4,5} and these are your terms.

    Do you understand that this is simply arithmetic and doing what you are told ?

    If, as you say, a_n= 2^n/n! then a_0= 2^0/0!= 1/1= 1. a_1= 2^1/1!= 2/1= 2.  a_1= 2^2/2!= 4/2= 2. a_3= 2^3/3!= 8/6= 4/3. a_4= 2^4/4!= 16/24= 2/3.
