Suppose that we have the following sequence :
a_1=1
a_n=1/2 a_(n-1) , for n> 1
we define a new sequence as such :
b_1=a_1
b_n=b_(n-1)+a_n
find the 50th term of the sequence b_n.
find the 1th term of the sequence b_n.

Let the closed interval [a , b] be the domain of function f. the domain of f(x - 3) is given by (a) the open interval (a , b) (b) the closed interval [a , b] (c) the closed interval [a - 3 , b - 3] (d) the closed interval [a + 3 , b + 3]
