Question

if a,b and c are in A.P with common difference 3 then find c-a​

Answer 1

Answer:

c-a = 6

Step-by-step explanation:

Let a = x

b = x+3

c= x+3+3 = x+6

Now,

c-a

= x+6-x

= 6

Answer 2

Answer:

6

Step-by-step explanation:

we know that the terms are in AP

thus,

b-a=c-b=3

or c-a=(c-b)+(b-a)

=3+3

=6
