Question

If a, b, c are three consecutive terms of an A.P., then 2b = ​

Answer 1

Answer:

b=( a+c)/2

Step-by-step explanation:

a , b , and c are three consecutive terms of AP .

c-b=b-a=d , where d is the common diff .

c-b=b-a , b+b=a+c , 2b =a+c , b= (a+c)/2

arithmatic mean of a and c is b

so b =(a+c)/2

value of b in terms of a and c ,

is b=(a+c)/2
