18 * 1 + 2 = 20
20 * 2 + 3 = 43
43 * 3 + 4 = 133
133 * 4 + 5 = 537
537 * 5 + 6 = 2691
2) Answer: D
652 – 42 = 636
636 – 52 = 611
611 – 62 = 575
575 – 72 = 526
526 – 82 = 462
3) Answer: A
12 + 76 = 88
88 + 74 = 162
162 + 72 = 234
234 + 70 = 304
304 + 68 = 372
4) Answer: E
147+ (1 + 4 +7)2 = 291
291 + (2 + 9 + 1)2 = 435
435 + (4 + 3 + 5)2 = 579
579 + (5 + 7 + 9)2 = 1020
1020 + (1+0+2+0)2=1029
