Answers:

1. 4

The series is:

267 – 4 = 263

263 – (4 + 8) = 251

251 – (12 + 8) = 231; not equal to 230

231 – (20 + 8) = 203

203 – (28 + 8) = 167

2. 1;

3. 2

The series is:

45 + 1 × 3.5 = 48.5

48.5 + 2 × 3.5 = 55.5

55.5 + 3 × 3.5 = 66: ; not equal to 65

66 + 4 × 3.5 = 80

80 + 5 × 3.5 = 97.5

4. 1

The series is:

856/2 + 24 = 452

452/2 + 24 = 250

250/2 + 24 = 149

149/2 + 24 = 98.5; not equal to 98

98.5/2 + 24 = 73.25

5. 4

6. 1

? = (27 + 25)/13 = 4

7. 2

? = (232 * 585)/100 / 150 = 9.048

8. 1

? = (9845 - 5620)/65 = 65

9. 3

? = [(134 * 17) - 177]/40 = 52.525

10. 1

? = 250/15 * 300/20 * 100/25 = 1000
