Given:
The given sequence is:
To find:
The recursive formula for 
, the nth term of the sequence.
Solution:
We have,
Here, the first term is 5.
The common difference is -7.
The recursive formula for the nth term of the sequence is
Where, 
is the common difference.
Putting 
in the above formula, we get
Therefore, the recursive formula for the nth term of the sequence is .
Answer: x^2 +6x +2x +36 = X^2 +8x + 36
Step-by-step explanation:
Answer:
d
Step-by-step explanation:
In the year 2009 there were 3500 birds on an island. If the bird population is declining 2.2% per year it means that in the year 2014 we will have 3500*
= 3131.57 birds.
The best prediction is that in the year 2014 the bird population will be 3132.
