# Product Series

The product series is divided into three module .

1. Series with constant quotient
2. Series with increasing quotient
3. Series with decreasing quotient

### Series with constant quotient

In the series of constant quotient of product series, each term is multiplied by a constant to get the next term.

Example 3,12,48,192___
A) 777
B) 770
C) 766
D) 768

Answer:D) 768

Explanation:Here each term is multiplied by 4 to get the next term.So the answer is 192*4=768

### Series with increasing quotient

In the series of increasing quotient the term are multiplied by a variable to get the next term.The variable are also a certain order and in a increasing order.

Example: 4,4,8,24,96........
A) 490
B) 480
C) 500
D) 470

Answer:B) 480

Explanation: Here the 1st term is multiplied by 1to get the second term.Then 2 nd term is multiplied by 2 to get the 3rd number..and so on.so answer is 96*5=480

### Series with decreasing quotient

In the series of decreasing quotient the term are multiplied by a variable to get the next term.The variable are also a certain order and in a decreasing order.

Example: 6,24,72,144.......
A) 144
B) 140
C) 145
D) 150

Answer:A) 20

Explanation: Here the 1st term is multiplied by 4 to get the second term.Then 2 nd term is multiplied by 3 to get the 3rd term and so on.so answer is 144*1=144
