**5 (a) (b) (c) (d) (e)**

**What will come in place of (b) ?**

(a) 139

(b) 163

(c) 161

(d) 157

(e) None of these

**Q7. 4 13 40 135 552 2765**

**2 (a) (b) (c) (d) (e)**

**What will come in place of (c) ?**

(a) 123

(b) 133

(c) 127

(d) 131

(e) None of these

**Q8. 5 12 4 10 3 8**

**6 (a) (b) (c) (d) (e)**

**What will come in place of (d) ?**

(a) 3

(b) 5

(c) 4

(d) 7

(e) None of these

**Q9. 3 13 37 87 191 401**

**1 (a) (b) (c) (d) (e)**

**What will come in place of (d) ?**

(a) 169

(b) 161

(c) 171

(d) 159

(e) None of these

**Q10. 8 4 6 15 52.5 236.25**

**12 (a) (b) (c) (d) (e)**

**What will come in place of (c) ?**

(a) 23.5

(b) 16.5

(c) 22.5

(d) 22.25

(e) None of these

Similarly, 5×6+1=31

31×5+8=163

Hence, 163 will come in place of (b).

13 = 4 × 1 + 1 × 9

40 = 13 × 2 + 2 × 7

135 = 40 × 3 + 3 × 5

552 = 135 × 4 + 4 × 3

2765 = 552 × 5 + 5 × 1

Similarly,

(a) = 2 × l + 1 × 9 = 11

(b) = 11 × 2 + 2 × 7 = 36

(c) = 36 × 3 + 3 × 5 = 123

Hence, 123 will come in place of (c).

Hence, 4 will come in place of (d).

(7, 11, 13, 17, 19, ..... are consecutive prime numbers)

Hence, 159 will come in place of (d).

Hence, 22.5 will come in place of (c).

*Solutions (6-10):*

**S6. Ans.(b)****Sol.**The given series is based on the following pattern:×6+1,×5+8,×4+27,×3+64,×2+125Similarly, 5×6+1=31

31×5+8=163

Hence, 163 will come in place of (b).

**S7. Ans.(a)****Sol.**The given series is based on the following pattern13 = 4 × 1 + 1 × 9

40 = 13 × 2 + 2 × 7

135 = 40 × 3 + 3 × 5

552 = 135 × 4 + 4 × 3

2765 = 552 × 5 + 5 × 1

Similarly,

(a) = 2 × l + 1 × 9 = 11

(b) = 11 × 2 + 2 × 7 = 36

(c) = 36 × 3 + 3 × 5 = 123

Hence, 123 will come in place of (c).

**S8. Ans.(c)****Sol.**The given series is based on the following pattern: ×2+2,÷2-2,×2+2,÷2-2………..Hence, 4 will come in place of (d).

**S9. Ans.(d)****Sol.**The given series is based on the following pattern:×2+7,×2+11,×2+13,×2+17,×2+19(7, 11, 13, 17, 19, ..... are consecutive prime numbers)

Hence, 159 will come in place of (d).

**S10. Ans.(c)****Sol.**The given series is based on the following pattern:×0.5,×1.5,×2.5…….Hence, 22.5 will come in place of (c).
