Question

The common difference of ap 1/c,1-c/c,1-2c/c,......is

Answer 1

Answer:

ap is 1/c, 1-c/c, 1-2c/c,.....

case1:- take first and second term

D= 1-c/c - 1/c

1-c -(1) /c

-c/c = -1

case2:- take second and third term

D = 1-2c/c -1-c/c

1-2c - (1-c) /c

1-2c -1+c/ c

-c/c = -1

so the common difference of the ap 1/c, 1-c/c, 1-2c/c is -1
