Math patterns. The next 3 numbers in the patterns are?

Question

NEXT THREE NUMBERS PLEASE
18,9,0,-9 . . .
6,8,12,18. . .
-11,-6,-1,4. . .
9,10,13,18. . .
1,7,19,37. . .

Answer 1

1) -18, -27, -36
(Subtract 9 from each number to get the next.)

2) 26, 36, 48
(Add 2, add 4, add 6, add 8, etc. -- each time the number to add increases by 2.)

3) 9, 14, 19
(Add 5 to each number to get the next)

4) 25, 34, 45
(Add 1, add 3, add 5, add 7, add 9, etc. -- each time, the number to add increases by 2)

5) 61, 91, 127
(Add 6, add 12, add 18, add 24, add 30, etc. -- each time, the number to add increases by 6)

Answer 2

18,9,0,-9,-18,-27,-36,-45,-54 and so on. Just subtract 9 from the previous value

6,8,12,18, 26,36,48,62,78,96 and so on. Add the factors of 2 in the ascending order like add 2 then 4 then 6 then 8 then 10 and so forth

-11,-6,-1,4,9,14,19,24,29,34,39. Just add 5 to the previous number. -11+5= -6, -1+5= 4
9,10,13,18,25,34,45. The sequence is by adding the previous result with the next odd number. 9
1=10. 1 is the first odd number and 10+3=13. 3 is the next odd number and so on

1,7,19,37, 61,91,127. The sequence is by adding the factors of 6. Adding 7+12=19. Here 12 is the factor of 6. 19+18=37. Here again 18 is the factor of 6.
