In an `AP`, as `a_7=9` and `a_1*a_2*a_7` an to as is least, then the common difference is:

A sequence a_n , n in N be an A.P. such that a_7 = 9 and a_1 a_2 a_7 is least, then the common difference is:

A sequence a_n , n in N be an A.P. such that a_7 = 9 and a_1 a_2 a_7 is least, then the common difference is:

If an AP a_7=9 and a_1a_2a_7 is least , then common difference is

If in an A.P. a_(7)=9 and if a_(1)a_(2)a_(7) is least, then common difference is _____

The sixth term of an A.P., a_1,a_2,a_3,.............,a_n is 2 . If the quantity a_1a_4a_5 , is minimum then then the common difference of the A.P.

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:

Let a_1,a_2,....a11 are in incresing A.P.and if varience of these number is 90 then value of common difference of A.P. is.

Let A_1 , A_2 …..,A_3 be n arithmetic means between a and b. Then the common difference of the AP is
