The first and the last terms of an A.P.are a and l respectively.Show that the sum of nth term from the beginning and nth term from the end is a+l

The first and last terms of an A.P. are a and l respectively. Show that the sum of nth term from the beginning and nth term from the end is a + l.

Prove that the sum of nth term from the beginning and nth term from the end of an A.P. is· constant.

The first and last term of an A.P. are a and l respectively. If S be the sum of all the terms of the A.P., them the common difference is

The first and last term of an A.P. are a and l respectively. If S be the sum of all the terms of the A.P., them the common difference is

If the first,second and nth terms of a A.P. are respectively a,b and c then prove that the sum of n terms of this series is

Find the nth term of an AP from the end

The first and last terms of an A.P. are a and l respectively. If S be the sum of the terms then show that the common difference is (l^(2) - a^(2))/(2S - (l+a)) .

If an A.P. consists of n terms with first term a and n^(th) term l then show that the sum of the m^(th) term from the beginning and the m^(th) term from the end is (a+l) .
