If `log_(2)(5.2^(x)+1),log_(4)(2^(1-x)+1)` and 1 are in A.P,then x equals

If 1,log_(2)(3^(1-x)+2),log_(2)(4*3^(3)-1) are in A.P then x equals to

If 1,log_(9)(3^(1-x)+2),log_(3)(4*3^(x)-1) are in A.P then x equals to

If log_(10) 2, log_(10)(2^(x) -1) , log_(10)(2^(x)+3) are in AP, then what is x equal to?

If log_(10)(2),log_(10)(2^(x)+1),log_(10)(2^(x)-3) are in A.P then x is equal to (i)log_(2)(5)( ii) log_(2)(-1) (iii) log_(2)((1)/(5))( iv) log_(5)(2)

If 1,log_(3)sqrt(3^(1-x)+2),log_(3)(4*3^(x)-1) are in AP then x equals

log_(2)(x^(2)-1)=log_((1)/(2))(x-1)
