Solutions:

1. The series is Ã—1, Ã—2, Ã—3, Ã—4, Ã—5,…
2. The series is +13, +23, +33, +43, +53,…
3. The series is +32, +22, +32, +22, +32…
4. The series is â€“51, â€“52, â€“53, â€“51, â€“52,…
5. The series is Ã·8, Ã·9, Ã·8, Ã·9, Ã·8…

6. The series is Ã—6, Ã—5, Ã—4, Ã—3, Ã—2…

Hence, number = 7800 Ã— 6 = 46800

7. The series is +22, +23, +24, +25, +26…

Hence, number = 19 + 24 = 19 + 16 = 35

8. The series is Ã—3 â€“ 5

Hence, number = 205 Ã— 3 â€“ 5 = 615 â€“ 5 = 610

9. The series is Ã—5, Ã—6, Ã—5, Ã—6, Ã—5…

Hence, number = 210 Ã— 5 = 1050

10. The series is â€“18, â€“17, â€“16, â€“15, â€“14…

Hence, number = 495 â€“ 17 = 478
