since a,b and c are in APso b-a=c-b(b-a)/(c-b)=1so option c)1 is the correct answer

options c is the right answer

option C=1 is correct answer.

b-a/c-b = 0 , b- a= 0 , b/a

option c is.correct answer.

option c =1 is right

(c) 1 is the correct answer

option C is the right answer

"C" is the right option I.e 1.

(b) 0 answer your question

answer is 1becuse a-b =common defferent and c-d also common defferent then common defferent /common defferent=1

option c is the right answer

option (c) 1 is the correct answer to this question .

since a,b and c are in AP so b-a=/(c-b)=1so option c ) 1 is the right answer

options c is the rite ans

option .c. is the right answer.

option c is the right

1 is the correct answer

1 is the correct answer

(c) 1 is the best answer

c is the right answer

the correct answer is (c) 1

option c is the correct answer

option is the right answer

option c is right ... bcz they r in a.p so b-a=c-a. then , b -a / c-b =1

option c is the correct

C(1) is the correct option

Option (C)is correct answer for me

so simple its answer is 1 means option C

ans option c right answer hoga

option C is the best answer

0

c is a correct answers

option. C. is the correct answer h

the correct answer is option (c)1

(c) 1 is the right answer

1 is the perfect answer

b - a = c- b so, b-a/c-a=1

answer is 1 because b-a=difference. c-b=difference. d/d=1

option c is right one

b-a = dc-b = dd/d=1 C) 1 is the answer

c is the answer hoga

if a,b and c are in A.Pthen b-a=c-b ( because all padanter is same)or b-a/c-b=1 answer

option c=1 correct answer

if a,b and c are in A.P then we know that b-a=c-bor b-a/c-b=1there for according to question answer will be option (c)

option c)1 is the correct answer

option C =1 is correct answer

c ) 1 ,, b -a =d c--b =d

c is the right answer

given,a b and c in A.Plet , (d)=rSo, b-a=r and c-b = r than b-a/c-a=r/r. = 1

so option (c)is right.
