The pattern of the given number series is as following-
⇒ 4
⇒ 4 × 1 + 1 = 5,
⇒ 5 × 2 + 1 = 11,
⇒ 11 × 3 + 1 = 34,
⇒ 34 × 4 + 1 = 137,
⇒ 137 × 5 + 1 = 686
Hence, the required number in the place of the question mark is 686.
⇒ 4
⇒ 4 × 1 + 1 = 5,
⇒ 5 × 2 + 1 = 11,
⇒ 11 × 3 + 1 = 34,
⇒ 34 × 4 + 1 = 137,
⇒ 137 × 5 + 1 = 686
Hence, the required number in the place of the question mark is 686.
