6) 6,9,11,13,17,20,22,24,28,x
Difference is repeating like 3,2,2,4,3,2,2,4
so x-28 should be 3
x-28=3
x=31

Ans : 31

7) I guess question might be 10,15,12,17,14,19,x

2*5=10 2*7+1=15

2*6=12 2*8+1=17

2*7=14 2*9+1=19

2*8=16

so ans : 16

Q3) -5,1,-11,23,29,17,-20,-14
sol: group these numbers in this way:
(-5,1,-11)=(-5+6=1 ,-5-6=-11)
(23,29,17)=(23+6=29 , 23-6=17)
so similary (-20,-14.?)=(-20+6=14,-20-6=-26(ans)) i.e ans is -26

Q8) 6,3,3,9,12,5,7,35,8,6,2,?
sol:
here in this series group the numbers in this way
(6,3,3,9) (12,5,7,35) (8 ,6,2,?)
here addition of two middle element give the first element of a group as output and there multiplication gives the last element of the group as an output

(69) (12 35) ( 8 12(ans))
i.e ans is 12

Q 9) -5 1 -11 23 29 17 -20 -14 ?
sol:group thses numbers as
(-5 ,1,-11) (23 ,29,17) (-20 ,-14 ,?)
-5+6=1 23+6=29 -20+6=-14
-5-6=-11 23-6=17 -20-6=-26(ans) i.e ans is -26

Q6) 6,9,11,13,17,20,22,24,28
sol: 6+3=9
9+2=11
11+2=13
13+4=17
now again
17+3=20
20+2=22
22+2=24
24+4=28
so in this way '3' should be added to 28(28+3=31(ans))
i.e 28+3=31(ans)
31+2=33
33+2=35
35+4=39
