Given p A.P.’s, each of which consists of n terms. If their first terms are 1, 2, 3, ...., p and common differences are
1, 3, 5, ...., 2p – 1 respectively, then sum of the terms of all the progressions is
1, 3, 5, ...., 2p – 1 respectively, then sum of the terms of all the progressions is
- \(\frac{1}{2} \mathbf{p} \quad(\mathbf{p}+1)\)
- \(\frac{1}{2} n(p+1)\)
- np (n + 1)
- none of these
Answer
(A) 1 2 p ( p +1)
