The pattern of the given number series is as:
⇒ 2,
⇒ 2 × 1 + 1 = 3,
⇒ 3 × 2 + 2 = 6 + 2 = 8, (instead of 9)
⇒ 8 × 3 + 3 = 24 + 3 = 27,
⇒ 27 × 4 + 4 = 108 + 4 = 112,
⇒112 × 5 + 5 = 560 + 5 = 565,
⇒ 565 × 6 + 6 = 3390 + 6 = 3396,
Hence, the wrong term of the given number series is 9. The correct term is 8.
⇒ 2,
⇒ 2 × 1 + 1 = 3,
⇒ 3 × 2 + 2 = 6 + 2 = 8, (instead of 9)
⇒ 8 × 3 + 3 = 24 + 3 = 27,
⇒ 27 × 4 + 4 = 108 + 4 = 112,
⇒112 × 5 + 5 = 560 + 5 = 565,
⇒ 565 × 6 + 6 = 3390 + 6 = 3396,
Hence, the wrong term of the given number series is 9. The correct term is 8.
