If the first three terms of an A.P are b, c and 2b, then find the ratio of b and c

If the first three terms of an A.P. are b, c and 4b, then find the ratio of b and c.

The sum of the first three terms of an A.P is 33 . If the product of the first terms and third term exceeds the 2nd term by 29 then find the A.P . The pth qth and rth term of an A.P . Are a b and c respectively . Prove that a (q-r)+ b(r-P)+c(p-q)=0

If the first, second and the last terms of an A.P. are a,b,c respectively, then the sum of the A.P. is

If the first, second and the last terms of an A.P. are a,b,c respectively, then the sum of the A.P. is

Let a,b and c be in G.P. with common ratio r, where a != 0 and 0 lt r le (1)/(2) . If 3a, 7b and 15c are the first three terms of an A.P., then the 4^(th) term of this A.P. is

Let a, b and c be in GP with common ratio, r where a !=0 and 0 lt r le (1)/(2) . If 3a, 7b and 15 c are the first three terms of an AP, then the 4th term of this AP is

Let a, b and c be in GP with common ratio, r where a !=0 and 0 lt r le (1)/(2) . If 3a, 7b and 15 c are the first three terms of an AP, then the 4th term of this AP is

If the sides a, b, c of a triangle are in A.P., then find the value of tan frac (A)(2)+ tan frac (C)(2) in terms of cot frac (B)(2) .

If first term of an A.P is a , second term is b and last term is c , then show that sum of all the terms is ((a+c)(b+c-2a))/(2(b-a)) .
