If the `28^(th)` term of a A.P is zero then its `(72^(th) term):(39^(th) term)` is

If 19^(th) term of a non-zero A.P. is zero, then ( 49^(th) term) : ( 29^(th) term) is

If 19th term of a non-zero AP is zero, then its (49th term) : (29 th term) is

If the n^(th) term of an A.P is (5n-2) ,find its 19^(th) term

If the 9^(th) term of an A.P. is zero, then prove that 29^(th) term is double of 19^(th) term.

The m^(th) term of an A.P. is n and n^(th) term is m its p^(th) term is

If the 10^(th) term of an A.P. is 1/5 and its 20^(th) term is 1/3 , then the sum of its first 150 terms is:

If m times the m^(th) term of an A.P. is equal to n times its n^(th) term , then show that (m+n)^(th) term of the A.P. is zero .

If the 9th term of an AP is zero, then prove that its 29th term is twice its 19th term.

If the 2^(nd) term of an A.P. is 8 and the 5 ^(th) term is 17, find its 19^(th) term.

If sum of the 3 ^(rd) and the 8^(th) terms of A.P. is 7 and the sum of the 7^(th) and the 14 ^(th) terms is -3, find the 10^(th) term.
