Consider an A.P.: a1,a2,…,ana_1, a_2, \ldots, a_n; a1>0a_1 > 0. If a2−a1=−34a_2 - a_1 = \dfrac{-3}{4}, an=14a1a_n = \dfrac14 a_1, and ∑i=1nai=5252\displaystyle\sum_{i=1}^{n} a_i = \dfrac{525}{2}, then ∑i=117ai\displaystyle\sum_{i=1}^{17} a_i is equal to
  1. (1)476
  2. (2)952
  3. (3)238
  4. (4)136
