(a) 950

(b) 1418

(c) 5675

(d) 2147

(e) 1077

**S12. Ans.(e)**

**Sol.**

The pattern of the number series is :

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 not 1077

1075 – 53 =950

Wrong number=1077
