Answer:
Pattern rule tells us the start number of pattern and how the pattern continues.
For instance, 5, 8, 11, 14 , 15....
Step-by-step explanation:
Pattern rule tells us the start number of pattern and how the pattern continues.
For instance, 5, 8, 11, 14 , 15....
In the above sequence, it starts with 5 and add 3.
Here the common difference between each successive term is 3.
The rule = first + 3
Let's take "a1" is the first term. "n" is the number of terms, "d" is the common difference
an = a1 + (n-1)d
Here a1 = 5
Let's find the second term, n = 2
a2 = 5 + (2 -1)d
a2 = 5 + (1)(3)
a2 = 8
Similarly, we can find the other terms using the rule
an = a1 + (n-1)d
Hope this will helpful.

approximation for the human population (in billions) of Earth in 2020?
Answer:
9.89 billion
Step-by-step explanation:
At that rate of growth, the population is multiplied by 1.023 each year. After 22 years, the population would be ...
6·1.023^22 ≈ 9.89 . . . billion
Answer:
Let the equation for the population (P) growth be given by
P = P0ert, where P0 is the initial population in billioins at time t,
t is the number of years since 1987,
r is the rate of growth of population/year
In this case P0 = 5 billion and r = 0.02. Putting these values into the equaation:
P = 5e0.02t
Year 1995 is 8 years after 1987, then the population would be
P = 5e0.02*8 = 5e0.16 ≈ 5.87 billion people
