Answer» The pattern of the given SERIES: Number + [(sum of digits)² + 1] = new number ⇒ 41 + ((4 + 1)² + 1) = 41 + (25 + 1) = 41 + 26 = 67 ⇒ 67 + ((6 + 7)² + 1) = 67 + (169 + 1) = 67 + 170 = 237 ⇒ 237 + ((2 + 3 + 7)² + 1) = 237 + (144 + 1) = 237 + 145 = 382 ⇒ 382 + ((3 + 8 + 2)² + 1) = 382 + (169 + 1) = 382 + 170 = 552 Then, 382 is the CORRECT term in place of 434. ∴ 434 is the wrong term in the series.

Answer»

The pattern of the given SERIES:

Number + [(sum of digits)² + 1] = new number

⇒ 41 + ((4 + 1)² + 1) = 41 + (25 + 1) = 41 + 26 = 67

⇒ 67 + ((6 + 7)² + 1) = 67 + (169 + 1) = 67 + 170 = 237

⇒ 237 + ((2 + 3 + 7)² + 1) = 237 + (144 + 1) = 237 + 145 = 382

⇒ 382 + ((3 + 8 + 2)² + 1) = 382 + (169 + 1) = 382 + 170 = 552

Then,

382 is the CORRECT term in place of 434.

∴ 434 is the wrong term in the series.
