What will come in place of question mark (?) in the following number series?
12, 33, 96, ?, 852, 2553
134
275
285
534
The pattern of the given number series is as:
⇒ 12
⇒ 12 × 3 – 3 = 33,
⇒ 33 × 3 – 3 = 96,
⇒? 96 × 3 – 3 = 285,
⇒ 288 × 3 – 3 = 852,
⇒ 852 × 3 – 3 = 2553
Hence, the required term is 285.
