1. 1 √230= 15.2
The pattern adds the number to product
of a prime number and the number 6. 5
following it: The next term is obtained by adding the
26 + 7 x 8 = 82 number to the product of its digits.
82 + 11 x 12 = 214 267 + 84 = 351
214 + 13 x 14 = 396 351 + 15 = 366
396 + 17 x 18 = 702 366 + 108 = 474
702 + 19 x 20 = 1082 474 + 112 = 586
586 + 240 = 826
2. 1
The pattern is as follows: 7. 3
102 + 122 = 244 The pattern is as follows:
112 + 132 = 290 240 x 1.3 = 312.0
122 + 142 = 340 312.0 x 1.3 = 405.6
132 + 152 = 394 405.6 x 1.3 = 527.28

685.464 x 1.3 = 891.1032
3. 1
The series adds the product of the digits 8. 1
to the previous number: The pattern is as follows:
289 + 144 = 433 27 + 232 + 1 = 557
433 + 36 = 469 557 + 202 + 1 = 958

685 + 240 = 925 1248 + 142 + 1 = 1445
925 + 90 = 1015 1445 + 112 + 1 = 1567
4. 2 9. 2
The pattern is shown below: From the 3rd number, each successive
6909/3 + 45 = 3327 term is average of previous 2 terms:
3327/3 + 44 = 1365 (144 + 128)/2 = 136
1365/3 + 43 = 519 (128 + 136)/2 = 132
