Answer:its d
Step-by-step explanation:
Recognize the differnce of 2 perfect squares
a²-b²=(a-b)(a+b)
so
Answer:
Option (2)
Step-by-step explanation:
In an arithmetic progression,

First term of the progression,
a = 
Common difference 'd' = 
Recursive formula for the sequence,
a = 

By applying these rules in the recursive formula,


Common difference 'd' = 
Therefore, Option (2) will be the answer.
