**Directions (11-15): In the following number series only one number is wrong. Find out the wrong number.**

**Q11. 32 34 37 46 62 87 123**

(a) 34

(b) 37

(c) 62

(d) 87

(e) 46

**S11. Ans (a)**

**Sol.**

The pattern of the number series is :

32 + 12 = 32 + 1 = 33

33 + 22 = 33 + 4 = 37

37 + 32 = 37 + 9 = 46

46 + 42= 46 + 16 = 62

62 + 52= 62 + 25 = 87

Wrong number= 34

So, there should be 33 instead of 34.

**Q12. 7 18 40 106 183 282 403**

(a) 18

(b) 282

(c) 40

(d) 106

(e) 183

**S12. Ans (c)**

**Sol.**

The pattern of the number series is :

7 + 1 × 11 = 7 + 11 = 18

18 + 3 × 11 = 18 + 33 = 51

51 + 5 × 11 = 51 + 55 = 106

106 + 7 × 11 = 106 + 77 = 183

183 + 9 × 11 = 183 + 99 = 282

Wrong number= 40

So, there should be 51 instead of 40.

**Q13. 850 843 829 808 788 745 703**

(a) 843

(b) 829

(c) 808

(d) 788

(e) 745

**S13. Ans (d)**

**Sol.**

The pattern of the number series is :

850 – 1 × 7 = 843

843 – 2 × 7 = 829

829 – 3 × 7 = 808

808 – 4 × 7 = 780

780 – 5 × 7 = 745

745 – 6 × 7 = 703

Wrong number= 788

So, there should be 780 instead of 788.

**Q14. 33 321 465 537 573 590 600**

(a) 321

(b) 465

(c) 573

(d) 537

(e) 590

**S14. Ans (e)**

**Sol.**

The pattern of the number series is :

33 + 288 = 321

321 + 144 = 465

465 + 72 = 537

537 + 36 = 573

573 + 18 = 591

591 + 9 = 600

Wrong number= 590

So, there should be 591 instead of 590.

**Q15. 37 47 52 67 87 112 142**

(a) 47

(b) 52

(c) 67

(d) 87

(e) 112

**S15. Ans (a)**

**Sol.**

The pattern of the number series is :

37 + 1 × 5 = 42

42

52+3=67

67+
