Set 1
1. Answer : 2. The given number series is based on the following pattern
12×0.5+0.5 = 6.5
6.5×1+1 = 7.5
7.5×1.5 +1.5 = 12.75
12.75 ×2 +2 = 27.5
27.5×2.5+2.5 = 71.25 and
71.25×3+ 3 = 216.75
So the ans is 216.75

2. Answer : 1. The given number series is based on the following pattern
16 ×= 8 × 3=24
24 ×=12×3= 36
36 ×= 18×3 =54
54 ×=27×3 =81
81×= 121.5 then
121.6×= 182.25
So the ans is 182.25

3. Answer : 5. The given number series is based on the following pattern.
12×1=12
12 ×1.5 =18
18 × 2.5= 45
45×4= 180
180×6.5 = 1170
Here each no multiply with 1, 1.5, 2.5, 4, 6.5, __ In this series the sum any two no's is third no. So last no is 4+ 6.5 = 10.5, now last no multiply with 10.5
1170 ×10.5 = 12285
So the ans is 12285

4. Answer : 3. Here given number series is based on the following pattern
22+12=22+1=23
23+22=23+4=27
27+32=27+9=36
36+42=36+16=52
52+52=52+25=77 and
77+62=77+36=113
So the answer is 113

5. Answer : 4. The given number series is based on the following pattern
16×1–2=14
14×2–4=24
24×3–6=66
66×4–8=256
256×5–10=1270 and
1270×6–12=7608
So the ans is 7608

Set 2
1.Answer : 4. The series is based on the following pattern
2 ×3 + 5 =11
11× 4–6 = 38
38×5 + 7 =197
197×6 –8 =1174: it is not 1172
1174× 7 + 9 =8227
8227× 8–10 =65806
Clearly 1172 is the wrong number and it should be replaced by 1174

2. Answer : 1. The series is based on the following pattern
16 + 12 = 17 but not 19
17 + 22 = 21
21 + 32 = 30
30 + 42 = 46
46 + 52 = 71
71 + 62 = 107
Clearly 19 should be replaced by 17

3. Answer : 4. The series is based on the following pattern.
7+9=16
9+16=25
25+41=66 but not 68
41+66=107
66+107=173
So 68 should be replaced by 66

4. Answer : 3. The series is based on the following pattern
4×0.5 = 2
2×1.5 = 3 but not 3.5
3×2.5 = 7.5
7.5 ×3.5 = 26.25
26.25×4.5 = 118.25
So 3.5 should be replaced with 3

5. Answer : 2. The series is based on the following pattern.
16 × 0.25 =4
4× 0.5 =2
2 × 0.75 =1.5
1.5× 1.00 =1.5 but not 1.75
1.5×1.25= 1.875
So 1.75 should be replaced by 1.5


Set 3
1. Answer : 4. The series is based on the following pattern.
17+92 = 98
98+72 =147
147+52 =172
172+32 =181
181+12 =182
So the ans is 182

2. Answer : 5.
The series is based on the following pattern.
11 + 8 = 19
19 + 12 = 31
31 + 16 = 47
47 + 20 = 67
67 + 24 =91
So the ans is 91

3. Answer : 2. The series is based on the following pattern.
748 – 288 = 460
460 – 144= 316
316 –72 = 244
244 –36 = 208
208 –18 = 190


Set 4
1. Answer : 3. The series in the following pattern.
12 + 4 = 16
16 + 8 = 24
24 + 12 = 36
36 + 16 = 52 and
52 + 20 = 72

2. Answer : 4. The series in the following pattern.
17 + 22 =21
21 + 42 = 37
37 + 62 = 73
73 + 82 = 137
137 +102 = 237

3. Answer : 1. The series in the following pattern.
620 – 208 = 412
412 –104 = 308
308 –52 = 256
256–26 =230 and
230–13 = 217

Set 5
1. Answer : 1. The series in the following pattern.
153–3 = 150
150–6 = 144
144–12 = 132
132–24 =108
108 – 48 =60
So the ans is 60

2. Answer : 1. The series in the following pattern.
31 + 9 =40
40 +18 = 58
58 +27 =85
85 + 36 =121
121 + 45 =166


Set 6
1. Answer : 1. The series in the following pattern.
36 + 11 = 37
37 + 32 = 46
46 + 52 =71
71 + 72 = 120
120 + 92 = 201
201 +112 = 322
So the ans is 120

2. Answer : 2. The series in the following pattern.
12 + 8 = 20
20 +80 = 100
100+800 = 900
900 + 8000 = 8900
8900 + 80000 = 88900
88900 + 800000 = 888900

3. Answer : 5. The series in the following pattern.
7×1 = 7
7×2 = 14
14×3 = 42
42× 4 = 168
168× 5 = 840
840×6 =5040

4. Answer : 3. The series in the following pattern.
21 + 9 = 30
30 – 18 = 12
12 + 27 = 39
39 – 36 = 3
3 + 45 = 48
48 – 54 = –6

5. Answer : 4.
The series in the following pattern.
10×2 + 4 = 24
24×2 + 4 = 52
52×2 + 4 = 108
108×2 + 4 = 220
220×2 + 4 = 444
444×2 + 4 = 892
