325, 259, 202, 160, 127, 105, 94

Answer: Option C

Explanation:

The correct pattern is - 66, - 55, - 44, - 33, - 22, - 11.

So, 202 is wrong and must be replaced by (259 - 55) i.e. 204.

1236, 2346, 3456, 4566, 5686

Answer: Option D

The correct pattern in the series is + 1110.

So, 5686 is wrong and must be replaced by (4566 + 1110) i.e. 5676.

93, 309, 434, 498, 521, 533

The correct pattern is + 6^{3}, + 5^{3}, + 4^{3}, + 3^{3}, .....

So, 521 is wrong and must be replaced by (498 + 3^{3}) i.e. 525.
