Answer Key with Solutions:
1. C)309
7 x 1 – 2 = 5
5 x 2 – 3 = 7
7 x 3 – 4 = 17
17 x 4 – 5 = 63
63 x 5 – 6 = 309
2. A)52
50..50+(1^3+1) = 52
52+(2^3+1)=61.
61+(3^3+1)=89
89+(4^3+1)=154
154 + (5^3+1) = 280
3. C)57
17 + 1 x 2 = 19
19 + 2 x 3 = 25
25 + 3 x 4 = 37
37 + 4 x 5 = 57
57 + 5 x 6 = 87
4. E)66
3….5…9…15…23
…2….4….6….8…
Answer 43+23= 66
5. B)1182
26 x 6 – 12 = 144
144 x 4 + 14 = 590
590 x 2 – 16 = 1164
1164 x 1 + 18 = 1182
6. A)324
2916/3 = 972
972/3 = 324
324/3 = 108
108/3 = 36
36/3 = 12
7. D)343
Cube prime series 23,  33,  53, 73, 113
8. D)
2 x 1 + 9 = 11 x 2 + 8 = 30 x 3 + 7 = 97 x 4 + 6 = 394
9. A)
x 6 – 1, x 5 – 1, x 4 – 1, x 3 – 1 = 935 x 3 – 1 = 2804
10. C)
+3, +6, +12, +24, +48 = 51  + 48 = 99
16. A)
Here the sequence can be achieved by -72, -92, -112, -132, 152, 172, ……………
17. B)
Here the sequence can be achieved by adding +1, +2, +4, +8, +16, +32
