Answer:
8
Step-by-step explanation:
![a_{n} = a_{n-1}*r\\a_{8} = a_{7}*r\\a_{8}=16*\frac{1}{2} =8](https://tex.z-dn.net/?f=a_%7Bn%7D%20%3D%20a_%7Bn-1%7D%2Ar%5C%5Ca_%7B8%7D%20%3D%20a_%7B7%7D%2Ar%5C%5Ca_%7B8%7D%3D16%2A%5Cfrac%7B1%7D%7B2%7D%20%3D8)

7.68 × 108
Step-by-step explanation:
World population in 2013 was about 7.125 billion
In 2003 , it was about 6.357 billion
Increase = 2013 population- 2003 population
That’s 7.125 billion - 6.357 billion = 0.768 billion
A billion has 9 zeros. When you move The point one place to the right , it reduces the number of zeros by one. you now have
7.68 x 10^8
A kg is 1000 grams, so you would 1000*4.
