2 answers:
Answer:
The recursive formula for the arithmetic sequence is given by:
for 
where, d is the common difference.
Given the sequence:
-16,-7,2,11...
This is a arithmetic sequence:
and d = 9
Since,
-7-(-16) = -7+6 = 9,
2-(-7) = 2+7 = 9,
11-2 = 9 and so on...
⇒ common difference(d) = 9
Substitute in [1] we have;
for 
Therefore, the recursive formula for this arithmetic sequence is,

Answer:
4p^3q^2.
Step-by-step explanation:
The GCF of 4 and 8 is 8.
That of p^4 and p^3 is p^3,
and that of q^5 and q^2 is q^2.
So it is 4p^3q^2.
