Answer:
160
80
40
20
Step-by-step explanation:
You start with the first term that is given which would be 
b(1)=<u><em>160</em></u>
That would be our first term, then we multiply by 0.5 which would be 1/2 
which gives us 80 as it is a division
You take the next term that we have found (80) and then we do the same thing, multiply by 0.5 (1/2)
