If `a,b,c,d` be four disinct positive quantities in HP, then
(a) `a+dgtb+c`
(b)`adgt bc`

If a,b,c,d be four distinct positive quantities in HP, then (a) a+dgtb+c (b) adgt bc

If a,b,c,d be four distinct positive quantities in GP,then show that (a) a+dgtb+c

If a,b,c,d be four distinct positive quantities in GP,then (a) a+dgtb+c (b) c^(-1)d^(-1)+a^(-1)b^(-1)gt2(b^(-1)d^(-1)+a^(-1)c^(-1)-a^(-1)d^(-1))

If a,b,c,d be four distinct positive quantities in GP,then (a) a+dgtb+c (b) c^(-1)d^(-1)+a^(-1)b^(-1)gt2(b^(-1)d^(-1)+a^(-1)c^(-1)-a^(-1)d^(-1))

If a,b,c three unequal positive quantities in H.P .then

If a,b,c three unequal positive quantities in H.P .then

Q. If a, b,c and d are distinct positive no. in AP. then (A) ad lt bc (B) a+c lt b+d (c) a+d=2(b+c) (D) a+d=3(b+c)

Q. If a, b,c and d are distinct positive no in AP. then (A) ad

If a,b,c,d are four different positive numbers which are in A.P then prove that bc gt ad

If distinct and positive quantities a ,b ,c are in H.P. then (a) b/c= (a-b)/(b-c) (b) b^2>ac (c) b^2< ac (d) a/c=(a-b)/(b-c)
