If In`(a+c),ln(a-c),ln(a-2b+c)` are in `AdotPdot,` then `a , b , c ,a r einAdotPdot` (b) `a^2,b^2,c^2a r einAdotPdot` `a , b , c` are in `GdotPdot` (d) `a , b , c` are in `HdotPdot`

If log(a+c)+log(a+c-2b)=2log(a-c) then

If a^(x), b^(x) and c^(x) are in GP, then which of the following is/are true? (A) a, b, c are in GP (B) log a, log b, log c are in GP (C ) log a, log b, loc c are in AP (D) a, b, c are in AP

If lna, lnb, lnc are in A.P and lna-ln2b, ln2b-ln2b-ln3c, ln3c-lna are in A.P, then a:b:c is

log_(a)b = log_(b)c = log_(c)a, then a, b and c are such that

If A,B,C, are the angles of a triangle such that cot(A/2)=3tan(C/2), then sinA ,sinB ,sinC are in (a)AdotPdot (b) GdotPdot (c) HdotPdot (d) none of these

a,b,c are sides of a triangle and a,b,c are in GP log a-log2b,log2b-log3c and log3c-log a are in AP then

Suppose A, B, C are defined as A=a^2b+a b^2-a^2c-a c^2, B=b^2c+b c^2-a^2b-a b^2, a n dC=a^2c+a c^2-b^2c-b c^2, w h e r ea > b > c >0 and the equation A x^2+B x+C=0 has equal roots, then a ,b ,c are in AdotPdot b. GdotPdot c. HdotPdot d. AdotGdotPdot
