Question

find d
and write the next 4 terms of arthemic Progressions
5,3,1,........​

Answer 1

Answer:

Given A.P is

1,−2,−5,−8,....

hence the common difference is given by d=a

n+1

−a

n

by putting n=1 in above equation

d=a

2

−a

1

=(−2)−(1)

d=(−2−1)

d=−3

first term of this A.P is

a

1

=1

the nth term of this A.P is given by

a

n

=a

1

+(n−1)d

⟹a

n

=1+(n−1)(−3)

⟹a

n

=1−3n+3

⟹a

n

=4−3n….eq(1)
