Answer 1

Answer:

  see below

Step-by-step explanation:

The recursive function tells you the first term is 1. That is the meaning of ...

  $a_1=1$

It also tells you that to find the next term, you multiply this term by 1/2:

  $a_2=\dfrac{1}{2}a_1=\dfrac{1}{2}\cdot 1=\dfrac{1}{2}$

And, to find the next term, you multiply this term by 1/2:

  $a_3=\dfrac{1}{2}a_2=\dfrac{1}{2}\cdot\dfrac{1}{2}=\dfrac{1}{4}$

Then the first three terms are ...

  1, 1/2, 1/4
