Answers:
1. 3
1 + 5 = 6, 6 + 7 = 13, 13 + 9 = 22, ...
2. 5
There are two series,
S1 = 8 + 1 = 9, 9 + 2 = 11, 11 + 3 = 14, ...
S2 = 8 + 1 = 9, 9 + 1 = 10, 10 + 1 = 11, ...
3. 2
The series is:
3 × 1 + 2 = 5
5 × 2 + 3 = 13
13 × 3 + 4 = 43
43 × 4 + 5 = 177
177 × 5 + 6 = 891
891 × 6 + 7 = 5353
4. 3
There are two series:
S1 = 5 × 2 = 10, 10 × 2 = 20, 20 × 2 = 40 ...
S2 = 10 + 0 = 10, 10 + 0 = 10, 10 + 0 ...
5. 2
6 × 2 - 3 = 9, 9 × 2 - 5 = 13,
13 × 2 - 7 = 19, ...
6. 3
Let CP = x
SP = y
So, (y - x)/x * 100 = 50
y = 3x/2
3x/2 - 80 = x
x = 160
