The pattern is - 5 then +2. 2 and 4 are the next numbers in the series.
1. Each number is 1/2 of previous number.
The rule is: add 5, subtract 2, add 5, subtract 2, . . . Next number is 24.
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.
This looks like a (subtract 5; add 2) series, so the next numbers are: 2, 4, -1, 1
The Pattern is 1^2- 2^2- 3^2- 4^2- 5^2 or 1 - 4 - 9 - 16 - 25 The next number in the series is 6^2 or 36
22
The pattern is - 5 then +2. 2 and 4 are the next numbers in the series.
The next number in the series will be 66. The next number is found by adding the two previous numbers. (2+7=9, 9+7=16, etc...)
16
1. Each number is 1/2 of previous number.
The next number in the series 2-4-3-9-4 is 16. 2 squared is 4, 3 squared is 9, 4 squared is 16
The rule is: add 5, subtract 2, add 5, subtract 2, . . . Next number is 24.
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.
This looks like a (subtract 5; add 2) series, so the next numbers are: 2, 4, -1, 1
16
21 - each number in the series increases by the series 1,2,3,4,5.... Whereby 6 and 7 are separated by 1, 7 and 9 are separated by 2, 9 and 12 are separated by 3, 12 and 16 are separated by 4, so the next in the series would be 21 (16 and 21 are separated by 5).
