Answers and Explanations to Exercise Set 4, Section C, Number Series

1. (B) The series "123" is repeated.
2. (C) Each number increases by 4.
3. (E) Each number decreases by 1.
4. (A) The series "10 20 30" is repeated.
5. (B) The series "7 6" is repeated.

Note: The patterns should have been fairly easy to spot. They simply repeat the same pattern of numbers or contain numbers that increase or decrease by the same amounts.

Answers and Explanations to Exercise Set 5, Section C, Number Series

1. (A) Each number is repeated twice; each set of numbers increases by 1.
2. (D) Each number increases by 2.
3. (B) This one gets tricky as there are two alternating series within this grouping. To get a better picture, "select out" the first, third, fifth, and seventh numbers: 4 5 6 7. Say them to yourself. It becomes clear that this is a series of numbers, increasing by 1. Now, "select out" the second, fourth, and sixth numbers: 6 6 6 6. Here you can see that the number 6 is repeated, in between the numbers in the first series. Therefore, the next two numbers should be 6 and 8.
4. (E) Reciting this series in groups of three, you may hear a rhythm: "66 56 10, 46 36 10." The first two numbers in each group decrease by 10, with the third number being the number 10. Therefore, the numbers after 26 should be 16 and 10.
5. (C) Once again, reciting this series to yourself, you may hear a rhythm: "2 2 3, 3 2 3." There are groups of three numbers within this series, with the first number in each group increasing by 1 and the other two remaining the same: "2 2 3" "3 2 3" "4 2 _." Therefore, the next two numbers should be "3 5" - the last number in the third group and the first number in the fourth group of the series.

Answers and Explanations to Exercise Set 6, Section C, Number Series

1. (C) 1 (+1) 2 (+2) 4 (+3) 7 (+4) 11 (+5) 16 (+6) 22 (+7) 29 (+8) 37
2. (A) 45 (+5) 50 (-3) 47 (+5) 52 (-3) 49 (+5) 54 (-3) 51 (+5) 56 (-3) 53
3. (D) 2 (×2) 4 (×2) 8 (×2) 16 (×2) 32 (×2) 64 (×2) 128 (×2) 256
4. (B) 16 (÷2) 8 (×3) 24 (÷2) 12 (×3) 36 (÷2) 18 (×3) 54 (÷2) 27
5. (E) 26 (-3) 23 (+6) 29 (-4) 25 (+6) 31 (-5) 26 (+6) 32 (-6) 26 (+6) 32

Answers and Explanations to Exercise Set 7, Section C, Number Series

1. (A) 24(-6) 18 (+4) 22 (-6) 16 (+4) 20 (-6) 14 (+4) 18 (-6) 12 (+4) 16
2. (B) Each number is repeated three times and increases by 3.
3. (A) 3 × 0 = 0 3 × 1 = 3 3 × 2 = 6 3 ×3
4. (D) 48 (repeat) 48 (-10) 38(-1) 37 (repeat) 37 (-10) 27 (-1) 26 (repeat) 26 (-10) 16
5. (B) 21 (+13) 34 (+13) 47 (+13) 60 (+13) 73 (+13) 86 (+13) 99 (+13) 112
6. (E) 16 (÷2) 8 (×3) 24 (÷2) 12 (×3) 36 (÷2) 18 (×3) 54 (÷2) 27 (×3) 81
7. (C) 92 (-6) 86 (-5) "20" 81(-4) 77 (-3) "20" 74 (-2) 72 (-1) "20" 71
8. (D) Two alternating series, both decreasing by one: 41 "12" 40 "11" 39 "10" 38 "9" 37 "8"
9. (E) The numbers "7 and 6" are repeated.
10. (A) Groups of three numbers, increasing by 2. Each group begins one step up from the previous group. 14 (+2) 16 (+2) 18; +1 15 (+2) 17 (+2) 19; +1 16 (+2) 18 (+2) 20
11. (B) Each number is repeated one time more than the number before. 31 appears once; 30 appears twice; 29 appears three times. 28 would appear four times.
12. (C) The numbers are divided by 2, with the number repeated. 96 (÷2) 48 (repeat) 48 (÷2) 2 (repeat) 24 (÷2) 12 (repeat) 12 (÷2) 6 (repeat) 6
13. (D) A tricky alternating series of ×2 and ×3.
Explanation for question 13.
14. (A) The pattern repeats groups of three numbers descending by -1, -2, -3; -1, -2, -3. 34 (-1) 33 (-2) 31 (-3) 28 (-1) 27 (-2) 25 (-3) 22 (-1) 21 (-2) 19
15. (E) The pattern 86 27 41 is repeated.
16. (E) Another tricky one. 4 (×0) 0; 4 (×1) 4; 4 (×2) 8; 4 (×3) 12; 4 (×4) 16; 4...
17. (B) Each number is square in descending order by 1. 100 (10 ×10); 81 (9×9); 64 (8×8); 49 (7×7); 36 (6×6); 25 (5×5); 16 (4×4); 9 (3×3); 4 (2x2)
18. (D) A "0" comes between two alternating series of numbers increasing by 1.
Explanation for question 18.
19. (C) Each number is repeated three times. You must assume that the series continues in this way with 29 being repeated two additional times.
20. (C) Two alternating series of +3 and -7. 28 (+3) 31 (-7) 24 (+3) 27 (-7) 20 (+3) 23 (-7) 16
(+3) 19 (-7) 12
