In an A.P.t_(7)=15 then the value of common differenced that would make t_(2)t_(7)t_(12) greatest is

If a_(n) be the term of an A.P. and if a_(7)=15 , then the value of the common difference that could makes a_(2)a_(7)a_(11) greatest is:

If a_n be the term of an A.P. and if a_7=15 , then the value of the common difference that could makes a_2a_7a_12 greatest is:

If it,be the n^(th) term of an A.P and if t_(7)=9 then the value of the c.d.that would make t_(1)t_(2)t_(7), least is

For an A.P. if t_(7)=4.d=-4 .then a=…..
