The pattern of series is as follows :
6 x 7 + 72 = 42 + 49 = 91
91 x 6 + 62 = 546 + 36 = 582 ≠ 584
582 x 5 + 52 = 2910 + 25 = 2935
2935 x 4 + 4,sup>2 = 11740 + 16 = 11756
11756 x 3 + 32 =35268 + 9 = 35277Correct Option: C

The pattern of number series is follows:
9050 - 153 = 9050 - 3375 = 5675
5675 - 133 = 5675 - 2197 = 3478
3478 - 113 = 3478 - 1331 = 2147
2147 - 93 = 2147 - 729 = 1418
1418 - 73 = 1418 - 343 = 1075 ≠1077Correct Option: E
