Consider an `A. P .a_1,a_2,a_3,.....` such that `a_3+a_5+a_8 =11and a_4+a_2=-2` then the value of `a_1+a_6+a_7` is.....

If a_1, a_2, a_3 ,........ are in A.P. such that a_1 + a_5 + a_10 + a_15 + a_20 + a_24 = 225 , then a_1 + a_2+ a_3 + ......+ a_23 +a_24 is equal to

If a_1+a_2+a_3+......+a_n=1 AA a_1 > 0, i=1,2,3,......,n, then find the maximum value of a_1 a_2 a_3 a_4 a_5......a_n.

In an arithmetic sequence a_1 + a_3 = 12 and a_4+a_6 = 24 . Find the values of a and d

Three distinct numbers a_1 , a_2, a_3 are in increasing G.P. a_1^2 + a_2^2 + a_3^2 = 364 and a_1 + a_2 + a_3 = 26 then the value of a_10 if a_n is the n^(th) term of the given G.P. is:

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

The average of a_1, a_2, a_3, a_4 is 16. Half of the sum of a_2, a_3, a_4 is 23. What is the value of a_1

Let {a_n} be a GP such that a_4/a_6 =1 /4 and a_2 + a_5 = 216 . Then a_1 is equal to
