Find the common difference of am AP:
Solution: 
Given sequence is,
first term of this A.P is 
second term of this A.P is 
third term of this A.P is 
fourth term of this A.P is 
the condition for an sequence to be an A.P is their must be a common difference
putting n=1 in above equation
putting n=2 in above equation
putting n=3 in above equation

as we can see we get a  common difference for this sequence
hence this sequence forms  an A.P
with first term and
common difference
