Question

if if a b c are in AP find the value of B _ a /c_b​

Answer 1

Answer:

1

Step-by-step explanation:

If a,b,c are three distinct terms in AP, the difference if one term and its previous term will be equal to the common ratio 'r',

b-a=r also c-b=r

So,

(b-a)/(c-b)

=r/r

=1

Answer 2

Answer:

b = (a+c)/2

Step-by-step explanation:

Since,a,b,c are in A.P. Then,

Common Difference (d) = a2-a1 = a3-a2

d = b-a = c-b

Thus,

b-a = c-b

=> b + b = c + a

=> 2b = a + c

=> b = (a+c) / 2
