Let x be the annual growth rate, expressed as a decimal.
148=142(1+x)^{3}
1+x= \sqrt[3]{1.04225} =1.01389
the number of years between 1998 and 2013 is 15 years. The estimated population in 2013 is given by:
148(1.01389)^{15}=182\ million
The answer is 182 million.

What is the recursive rule for this geometric sequence? 1/2, -2, 8, -32
Gnesinka [82]

Answer:

see explanation

Step-by-step explanation:

A recursive rule allows us to find the term in a sequence from the previous term.

From the given geometric sequence find r the common ratio

r = \frac{-2}{\frac{1}{2} } = \frac{8}{-2} = - 4

Hence recursive rule is

a_{n+1} = - 4a_{n} ( a₁ = \frac{1}{2} )
