The common difference of the A.P. `1/3,(1-3b)/3,(1-6b)/3,\ dot` is `1/3` (b) `-1/3` (c) ` b` (d) `b`

The common difference of the AP (1)/(3), (1-3b)/(3), (1-6b)/(3) ,… is

Find the common difference of the A.P. : 3, 1, -1, -3, .......

The common difference of the A.P. 1/(2b),(1-6b)/(2b),(1-12 b)/(2b),... is 2b (b) -2b (c) 3 (d) -3

If (a)/(b)=(4)/(3), then (3a+2b)/(3a-2b)=?( a) -1 (b) 3 (c) 5(d)6

IF x,2y,3z are in A.P. where x,y,z are unequal number in a G.P., then the common ratio of this G.P. is (a) 3 (b) 1/3 (c) 2 (d) 1/2

Value of the D=|(1/a,bc,a^(3)),(1/b,ca,b^(3)),(1/c,ab,c^(3))| is

Three distinct A.P!'s have same first term, common differences as d_(1),d_(2),d_(3) and n^(th) terms as a_(n),b_(n),c_(n) respectively such that (a_(1))/(b_(1))=(2b_(1))/(d_(2))=(3c_(1))/(d_(3)). If (a_(7))/(c_(6))=(3)/(7) then (b_(7))/(c_(6)) is equal to

If (a)/(b)+(b)/(a)=-1, then a^(3)-b^(3)=1(b)-1 (c) (1)/(2)(d)0

If x^(2)+3x+3=0 and ax^(2)+bx+1=0 ,a,b in Q have a common root,then value of (3a +b) is equal to : (A) (1)/(3) (B) 1 (C) 2 (D) 4
