If `a,b,c` are in A.P.then `b-a=`

If a,b,c are in A.P.then ((a-c)^(2))/((b^(2)-ac)=)

If a,b,c are in A.P.then prove that the following are also in A.P.a^(2)(b+c),b^(2)(c+a),c^(2)(a+b)

Statement 1: The number of ways in which three distinct numbers can be selected from the set {3^(1),3^(2),3^(3),3^(100),3^(101)} so that they form a G.P.is 2500. Statement 2: if a,b,c are in A.P.then 3^(a),3^(b),3^(c) are in G.P.

In Delta ABC, if a,b,c are in A.P.then (tan A)/(2),(tan B)/(2),(tan C)/(2) are in

If a,b,c are in A.P.then prove that the following are also in A.P.a((1)/(b)+(1)/(c)),b((1)/(c)+(1)/(a)),c((1)/(a)+(1)/(b))

If a,b,c are in A.P.then prove that the following are also in A.P.(1)/(sqrt(b)+sqrt(c)),(1)/(sqrt(c)+sqrt(a)),(1)/(sqrt(a)+sqrt(b))

If a,b,c are in A.P.then prove that: (a-c)^(2)=4(b^(2)-ac)a^(3)+4b^(3)+c^(3)=3b(a^(2)+c^(2))

If a,b, and c are in A.P.then a^(3)+c^(3)-8b^(3) is equal to 2abc b.6abc c.4abc d.none of these

If a,b,c are in H.P., then (b+a)/(b-a)+(b+c)/(b-c)

If a,b,c are in G.P then (b-a)/(b-c)+(b+a)/(b+c)=
