AGP

Rita, Sita, Gita and Shyam are playing a bride game. It is four persons play and a pair of two-two persons as a partner is made A dack of 52 playing cards is distributed arounded the table clockwise in such a way that each person get 13 cards. (##AGP_EDG_MAT_X_BSC_SQP_T1_06_E01_026_Q01.png" width="80%"> Find the probability that the card drawn is a queen of black colour.

Given the sequence of numbers X_1,X_2,X_3,.....X_(2013) which satisfy X_1/(X_1+1)=X_2/(X_2+3)=X_3/(X_3+5)=....=,X_(2013)/(X_(2013)+4025) nature of the sequence is (i)A.P (ii)G.P (iii)H.P (iv)A.G.P

If lambda!=0,a,b,c,lambda are real such that a^(2)+b^(2)+c^(2)-2 lambda a-4b lambda-8 lambda c+21 lambda^(2)<=0 then (A) a,b,c are in A.P (B) a,b,c are in G.P (C) a,b,c are in H.P (D) a,b,c are in A.G.P

suppose x1,x2 are the roots of the equation ax^2+bx+c=0 and x3 and x4 are the roots of the equation px^2+qx+r=0 If a, b, c are in G.P. as well as x_1, x_2, x_3, x_4 are in G.P., then p, q, r are in (i) A.P (ii)G.P (iii)H.P (iv)A.G.P

The fourth term of the A.G.P. 6, 8, 8,…….. is

If the number 16, 20, 16, d form a A.G.P. then d can be equal to :

The sum (S_(oo)) of infinite terms of A.G.P, (r<1) then S_(oo) is
