Answer 1

hiii the answer to this question 5 is 55

Answer 2

On the first sequence you must find relations between the numbers. 
The difference between 6 and 9 is 3. 
Between 9 and 14 is 5. 
Between 14 and 21 is 7. 
21 and 30 is 9. 
It is easy to guess that you need to add a number to 6 (starting from 3) and adding two more each time, like this: 6+3=9 ; 9+5=14 ; 14+7=21 ; ... 
If you continue the sequence: 6, 9, 14, 21, 30, 41, 54, 69, 86.
