Answer: Given A.P is,
75,67,59,51,...…
first term of this A.P is a
1
=75
second term of this A.P is a
2
=67
third term of this A.P is a
3
=59
fourth term of this A.P is a
4
=51
common difference of an A.P is (i.e.,d=a
n+1
−a
n
)
putting n=1 in above equation
d=a
2
−a
1
=67−75=−8
hence,common difference d=−8
we know that nth term of an A.P is given by
a
n
=a
1
+(n−1)d
⟹a
n
=75+(n−1)(−8)
⟹a
n
=75−8n+8
