The series appears to be an arithmetic series in which the n'th term is 1.5 + (n - 1)2.5. If so, the next two terms are 11.5 and 14.
The numbers are increasing by 1,4,9,16,25,36.... which are square numbers so the next increase is 49. Making the next number in the sequence 141
They are a sequence of odd numbers. The next three in the sequence would be 17,19 & 21
The next three numbers in the sequence are 23, 25, and 27.
22.5, 33.75, 50.625...
36 - The sequence is deducting two from the difference between the two numbers each time.81-64=1764-49=15 therefore49-36=13It is squire of numbers in decending order9*9=818*8=647*7=496*6=36
15... you're dividing by 2 each time.

11, -10, 9

22.5, 33.75, 50.625...
63, 102, 165...
15 since you multiply by 3 then subtract 3 in sequence
