1. 1
680 - 5^2 = 655
655 + 7^2 = 704
704 - 9^2 = 623
623 + 11^2 = 744
744 - 13^2 = 575

2. 3
10 × 1/2 + 5 = 10
10 × 1 + 10 = 20
20 × 1 1/2 + 15 = 45
45 × 2 + 20 = 110
110 × 2 1/2 + 25 = 300
300 × 3 + 30 = 930

3. 3
1 × 2 + 4 = 6
6 × 5 - 8 = 22
22 × 8 + 12 = 188
188 × 11 - 16 = 2052
2052 × 14 + 20 = 28748

4. 4
50327 - 122 ÷ 7 = 7169
7169 + 112 ÷ 6 = 1215
1215 - 102 ÷ 5 = 223
223 + 92 ÷ 4 = 76
76 - 82 ÷ 3 = 4

5. 2
2 + 3 × 4 = 14
4 + 5 × 6 = 34
6 + 7 × 8 = 62
8 + 9 × 10 = 98
10 + 11 × 12 = 142
12 + 13 × 14 = 194

6. 3
The series is
5^3 – 1 = 124
6^3 – 1 = 215
7^3 – 1 = 342
8^3 – 1 = 511
9^3 – 1 = 728
10^3 – 1 = 999
Reqd answer = 728.

7. 1; The series is
