The next number is 2.
The series appears to be following a pattern where each number is the result of a mathematical operation on the previous numbers. In this case, the pattern seems to be adding consecutive odd numbers starting from 1. 1 + 8 = 9 9 + 9 = 18 18 + 7 = 25 25 + 2 = 27 27 - 6 = 21 Following this pattern, the next number in the series would be 21 + 1 = 22.
It is 5n+2 and so the next number is 22
The range of 10, 13, 22, 25, and 31 is 21.

13 18 16 21 19 24 22 27 25 ... . This series consists of adding 5 to the first number and subtracting 2 from the next number, repeating the sequence in that order.
The next number in the series 1 2 4 8 10 20 22 is

The next number is 17. You're adding 8, and then subtracting 5. So; 2 + 8 = 10 10 - 5 = 5 5 + 8 = 13 etc... 19 - 5 = 14 14 + 8 = 22 22 - 5 = 17
25-1=24 24-2=22 22-3=19 19-4=15 15-5=10 The next number in the series is 10.
