      Question

      What value should come in the place of (?) in the

      following number series? 100, 115, ?, 190, 250, 325
      A 172 Correct Answer Incorrect Answer
      B 180 Correct Answer Incorrect Answer
      C 145 Correct Answer Incorrect Answer
      D 193 Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      ATQ, 100 + 15 * 1 = 115 115 + 15 * 2 = 145 145 + 15 * 3 = 190 190 + 15 * 4 = 250 250 + 15 * 5 = 325 Here the pattern is: add 15 × 1, 15 × 2, 15 × 3, 15 × 4, 15 × 5. So the missing term is: 115 + 15 * 2 = 145 Hence 145 will come in place of (?)
