67, 131, and 259.
1 squared, 2 squared, 3 squared etc so the next 3 terms are 36,49 and 64.
multiply 3 subtract 2
If you mean: 12, 11, 9, 6, 2 then the next number is -3 Because they are being reduced by 1, 2, 3, 4 and then 5
-11
67, 131, and 259.
27 over 18 to the lowest terms is: 3 over 2 = 3/2 = 11/2 or 1.5
1 squared, 2 squared, 3 squared etc so the next 3 terms are 36,49 and 64.
18 over 12 in its lowest terms = 3/2 = 11/2 or 1.5
multiply 3 subtract 2
If you mean: 12, 11, 9, 6, 2 then the next number is -3 Because they are being reduced by 1, 2, 3, 4 and then 5

Actually the next number in the sequence is 17 A 19 , 23 , 29 , 31 ,.......... Prim number
-7 -11 -15 You subtract 4 each time
2 3 5 7 11 13 17 19 23 ... Prime numbers
It could be 6: 18 / 2 = 9, 9 + 2 = 11, 11 + 3 = 14, 14 / 2 = 7, 7 + 2 = 9, 9 + 3 = 12, ... So the next steps would be: 12 / 2 = 6, 6 + 2 = 8, 8 + 3 = 11, 11 / 2 = 5.5, 5.5 + 2 = 7.5, 7.5 + 3 = 10.5, 10.5 / 2 = 5.25, ...
the numbers next in series are 35,43,51,... any two consecutive terms has a difference of 8
