Find the sum of first 24 terms of the A.P. `a_(1) , a_(2), a_(3)`...., if it is know that `a_(1) + a_(5) + a_(10) + a_(15) + a_(20) + a_(24) = 225`

Find the sum of first 24 terms of the A.P.a-1,a_(2),a_(3),... if it is inown that a_(1)+a_(5)+a_(10)+a_(15)+a_(20)+a_(24)=225

Find the sum of first 24 terms of the A.P. a_1,a_2, a_3 ......., if it is inown that a_1+a_5+a_(10)+a_(15)+a_(20)+a_(24)=225.

Find the sum of first 24 terms of the A.P. a_1,a_2, a_3 ......., if it is inown that a_1+a_5+a_(10)+a_(15)+a_(20)+a_(24)=225.

Find the sum of first 16 terms of an A.P.a_(1),a_(2),a_(3)......... If it is known that a_(1)+a_(4)+a_(7),+a_(10)+a_(16)=147

If the sum of first 11 terms of an A.P., a_(1),a_(2),a_(3),.... is 0(a_(1)!=0) then the sum of the A.P., a_(1), a_(3),a_(5), ......,a_(23) is k a_(1) , where k is equal to :

a_(1),a_(2),a_(3),......,a_(n), are in A.P such that a_(1)+a_(3)+a_(5)=-12 and a_(1)a_(2)a_(3)=8 then

The successive terms of an A.P. are a_(1), a_(2), a_(3) ,….. If a_(6)+a_(9)+a_(12)+a_(15)=20 then sum_(r=1)^(20)a_(r) =

If a_(1), a_(2), a_(3),…….,a_(20) are in AP and a_(1) + a_(20) = 45 , then a_(1) + a_(2) + a_(3)+……+a_(20) is equal to

For the A.P., a_(1),a_(2),a_(3) ,…………… if (a_(4))/(a_(7))=2/3 , find (a_(6))/(a_(8))
