18 * 1 + 2 = 20
20 * 2 + 3 = 43
43 * 3 + 4 = 133
133 * 4 + 5 = 537
537 * 5 + 6 =Â 2691 (Not 2690)
2) Answer: C
8 * 2.5 = 20
20 * 2.5 = 50
50 * 2.5 = 125Â (not 122)
125 * 2.5 = 312.5
312.5 * 2.5 = 781.25
3) Answer: D
652 – 42 = 636
636 – 52 = 611 (Not 610)
611 – 62 = 575
575 – 72 = 526
526 – 82 = 462
4) Answer: A
8 * 2 – 2 = 14
14 * 2 – 2 = 26 (not 20)
26 * 2 – 2 = 50
50 * 2 – 2 = 98
98 * 2 – 2 = 194
