If log a, log b, log c are in A.P. then a,b,c are

If a,b,c are in G.P.,then prove that log a^(n),log b^(n),log c^(n)quad are in A.P.

If log( a+c), log(c-a) , log ( a-2b+c) are in A.P., then :

If log2,log(2^(n)-1) and log(2^(n)+3) are in AP,then n=

Suppose a,b,c gt 1 and n in N, n ge 2 . If log_(a)(n),log_(b)(n),log_(c )(n) are in A.P., then log_(a)b+log_(c )b =

If log2,log(2^n-1) and log(2^n+3) are in A.P. then n =
