r = -5
Step-by-step explanation:
common ratio (r) is found be dividing one term by its preceding term:

Answer:
A database management system is a software package designed to define, manipulate, retrieve and manage data in a database. A DBMS generally manipulates the data itself, the data format, field names, record structure and file structure. It also defines rules to validate and manipulate this data.
Step-by-step explanation:
Basically, factor
first distribute
a(b+c)=ab+ac
p(c-d)=pc-pd
now we have
pc-pd+c-d
grou the c's with c's and d's with d's
(pc+c)+(-pd-d)
undistribute c's and -d's
c(p+1)-d(p+1)
undistribute with (p+1) as the a
(p+1)(c-d)
tada
(p+1)(c-d)
