What are the first three terms of the sequence modeled by the recursive function an=1/2an-1 when a1=1?
a. 1, 1/2, 1/4
b. 1, 1/2, 0
c. 1, 2, 4
d. 1, 3/2, 2

Option A is correct that is

Step-by-step explanation:

We have been given a formula

We will put values of n in

when n=2 we get

when n=3

Therefore, Option A is correct that is
