1. The first and last term of an A.P are a and l respectively. If S is the sum of all the terms os the A.P and common difference is given by { l(square)-a(square) / k-(l+a) } , then k=
2. If the sum of first n even natural numbers is eaqual to the k times the sum of first n odd natural numbers, then k=
3. If S1 is the sum of an A.P of n odd number of terms and S2 the sum of the terms of the sries in odd places then S1/S2 =
4. If in an A.P S(n)=n(square)*p and S(m)=m(square)*p , where S(r) denotes the sum of r terms of the A.P , then S(p) is equal to
