##### 1. Question

21, 77, 211, 391, 697, 1077

The pattern adds the number to product of a prime number and the number following it:

21 + 7 x 8 = 77

77 + 11 x 12 = 209

209 + 13 x 14 = 391

391 + 17 x 18 = 697

697 + 19 x 20 = 1077

##### 2. Question

70, 132, 224, 354, 522

The pattern is as follows:

4

^{3}+ 6 = 70

5

^{3}+ 7 = 132

6

^{3}+ 8 = 224

7

^{3}+ 9 = 352

8

^{3}+ 10 = 522

##### 3. Question

176, 218, 234, 258, 340, 410

The series adds the product of the digits to the previous number:

176 + 42 = 218

218 + 16 = 234

234 + 24 = 258

258 + 80 = 338

338 + 72 = 410

##### 4. Question

14442, 5838, 2202, 800, 282, 98

The pattern is shown below:

14442/3 + 4

^{5}= 5838

5838/3 + 4

^{4}= 2202

2202/3 + 4

^{3}= 798

798/3 + 4

^{2}= 282

282/3 + 4

^{1}= 98

##### 5. Question

11.8, 12.6, 13.4, 14.3, 14.8

The pattern is shown below:

√140= 11.8

√160= 12.6

√180= 13.4

√200= 14.1

√220= 14.8

**Find the wrong term in the series given below.**

##### 6. Question

6. 211, 213, 219, 237, 281, 405

The next term is obtained by adding the number to the product of its digits.

211 + 2 = 213

213 + 6 = 219

219 + 18 = 237

237 + 42 = 279

279 + 126 = 405

##### 7. Question

30, 39.0, 50.7, 67.91, 85.683, 111.3879

The pattern is as follows:

30 x 1.3 = 39.0

39.0 x 1.3 = 50.7

50.7 x 1.3 = 65.91

65.91 x 1.3 = 85.683

85.683 x 1.3 = 111.3879

##### 8. Question

77, 303, 475, 595, 677, 727

The pattern is as follows:

77 + 15

^{2}+ 1 = 303

303 + 13

^{2}+ 1 = 473

473 + 11

^{2}+ 1 = 595

595 + 9

^{2}+ 1 = 677

677 + 7

^{2}+ 1 = 727

##### 9. Question

76, 140, 110, 124, 116, 120

From the 3rd number, each successive term is average of previous 2 terms:

(76 + 140)/2 = 108

(140 + 108)/2 = 124

(108 + 124)/2 = 116

(124 + 116)/2 = 120

##### 10. Question

77, 126, 164, 166, 202, 206

The next term is obtained by adding the number to the square of the last digit of the previous number.

77 + 7

^{2}= 126

126 + 6

^{2}= 162

162 + 2

^{2}= 166

166 + 6

^{2}= 202

202 + 2

^{2}= 206
