Answer:
see below
Step-by-step explanation:
The recursive function tells you the first term is 1. That is the meaning of ...
[tex]a_1=1[/tex]
It also tells you that to find the next term, you multiply this term by 1/2:
[tex]a_2=\dfrac{1}{2}a_1=\dfrac{1}{2}\cdot 1=\dfrac{1}{2}[/tex]
And, to find the next term, you multiply this term by 1/2:
[tex]a_3=\dfrac{1}{2}a_2=\dfrac{1}{2}\cdot\dfrac{1}{2}=\dfrac{1}{4}[/tex]
Then the first three terms are ...
1, 1/2, 1/4
