1.	1). 12242). 14063). 12404). 1357
Answer» The pattern of the given series: Number + (sum of middle two DIGIT)² = next number ⇒ 1224 + (2 + 2)² = 1224 + 4² = 1224 + 16 = 1240 ⇒ 1240 + (2 + 4)² = 1240 + 6² = 1240 + 36 = 1276 ⇒ 1276 + (2 + 7)² = 1276 + 9² = 1276 + 81 = 1357 ⇒ 1357 + (3 + 5)² = 1357 + 8² = 1357 + 64 = 1421 Then, 1421 is the correct term in PLACE of 1406. ∴ 1406 is the wrong term in the series.

Answer»

The pattern of the given series:

Number + (sum of middle two DIGIT)² = next number

⇒ 1224 + (2 + 2)² = 1224 + 4² = 1224 + 16 = 1240

⇒ 1240 + (2 + 4)² = 1240 + 6² = 1240 + 36 = 1276

⇒ 1276 + (2 + 7)² = 1276 + 9² = 1276 + 81 = 1357

⇒ 1357 + (3 + 5)² = 1357 + 8² = 1357 + 64 = 1421

Then,

1421 is the correct term in PLACE of 1406.

∴ 1406 is the wrong term in the series.
