For a G.P. If `a = 3 and, r = 2`, then `t_7` (A) `192` (B) `162` (C) `152` (D) `132 A`​

If for a G.P., r=2 and S_(8) =510, then : t_(3) =

If for a G.P., r=2 and t_(9) =128, then : a=

If for a G.P., S_(3) : S_(6) =125 : 152 then : r =

a,b,c are in G.P. and a+b+c=xb, x can not be (a) 2 (b) -2 (c) 3 (d) 4

If, for a G.P., t_(3) =0.08 and t_(7) =0.000128, then : (a,r) -=

If A D is median of A B C and P is a point on A C such that a r\ ( A D P):\ a r\ ( A B D)=2:3,\ then a r( P D C): a r\ ( A B C) is 1:5 (b) 1:5 (c) 1:6 (d) 3:5

If in a g.P. { t_(n)) it is given that t_(p+q) =a and t_(p-q) = b then : t_(p) = (A) (ab)^(1/2) (B) (ab)^(1/3) (C) (ab)^(1/4) (D) none of these

Let a,b,c are 7^(th), 11^(th) and 13^(th) terms of constant A.P if a,b,c are also is G.P then find (a)/(c ) (a) 1 (b) 2 (c) 3 (d) 4
