If b-c,2b-lambda,b-a " are in HP, then " a-(lambda)/(2),b-(lambda)/(2),c-(lambda)/(2) are in

If a,b,c are in A.P,then are a lambda,b lambda and c lambda in AP?

If |(a^(2), b^(2), c^(2)),((a+lambda)^(2), (b+lambda)^(2), (c+lambda)^(2)),((a-lambda)^(2), (b-lambda)^(2), (c-lambda)^(2))|=klambda|(a^(2), b^(2),c^(2)),(a,b,c),(1,1,1)|,lambda ne 0 then k is equal to

If bar(a),bar(b),bar(c) are non coplanar vectors and lambda is a real number then [lambda(bar(a)+bar(b))lambda^(2)bar(b)lambdabar(c)]=[bar(a)bar(b)+bar(c)bar(b)] for

If p lambda^(4) + q lambda^(3) + r lambda^(2) + s lambda + t = |{:(b^(2)+c^(2), a^(2) + lambda , a^(2) + lambda),(b^(2)+lambda,c^(2)+a^(2),b^(2)+lambda),(c^(2)+lambda,c^(2)+lambda,a^(2)+b^(2)):}| is an identity in lambda wherep, q, r,s , t are constants, then the value of t is

If plambda ^(4)+qlambda^(3)+rlambda ^(2)+ s lambda +t= |{:(lambda^(2)+3,lambda -1, lambda +3),(lambda^(2)+1,2-lambda ,lambda-3),(lambda^(2)-3,lambda+4,3lambda):}| then t is equal to : a)33 b)22 c)21 d)57

If a,b,c are in AP and (a+2b-c)(2b+c-a)(c+a-b)=lambdaabc , then lambda is

If a,b,c are in AP and (a+2b-c)(2b+c-a)(c+a-b)=lambdaabc , then lambda is
