11, -10, 9

It is 30; the first, third, and fifth numbers form the sequence 12, 18, 24. The second, fourth, and sixth numbers follow the sequence 11, 14, 17. Logically, the seventh number must be 24 + 6, so 30.

The next figure would be 21, followed by 11 & 10.

14

Without further terms in the sequence, it is impossible to determine what the rule in the sequence is.

The answer is 15 because the pattern is subtract one, add two

It would be 6. The pattern is -divide by 2 add 2 add 3- repeat.

12 11 18 14 24 17 30 20.. i think ;-) pattern: 18-12 = 6 14-11 = 3 24-18 = 6 17-14 = 3 i hope that helps.

18 9 11 14 7 9 12 the series is like 18/2= 9 9+2=11 11+3=14 14/2=7 7+2=9 9+3=12 so next number will be.. 12/2=6 then 6+2=8 8+3=11

Think it's 30...then 20

17?

It looks like two different operations in a pattern. Taking 4 multiply by 3 = 12. Taking 12 add 2 = 14. Taking 14 multiply by 3= 42 ........ so next is ..... taking 42 add 2 = 44.
