Let `a_1, a_2, a_3, ,a_n` be in G.P. such that `3a_1+7a_2+3a_3-4a_5=0.` Then common ratio of G.P. can be `2` b. `3/2` c. `5/2` d. `-1/2`

Let a_1,a_2,a_3…… ,a_n be in G.P such that 3a_1+7a_2 +3a_3-4a_5=0 Then find common ratio of G.P.

Let a_1,a_2,a_3 ......, a_n are in A.P. such that a_n = 100 , a_40-a_39=3/5 then 15^(th) term of A.P. from end is

If the first term of a G.P. a_1, a_2, a_3, ddot is unity such that 4a_2+5a_3 is least then the common ratio of G.P. is -2//5 b. -3// c. //5 d. none of these

Let a_1,a_2," ..."a_10 be a G.P. If a_3/a_1=25," then "a_9/a_5 equals

a_1,a_2, a_3, ,a_n are in A.P. and a_1+a_3+a_5+a_7+a_9=20 then a_5 is 2 2. 7 3. 3 4. 4 5. 5
