24, they are going up in 3's, 13, 16, 19 and 18, 21 so next number is 24.
The pattern is - 5 then +2. 2 and 4 are the next numbers in the series.
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 rule is: add 5, subtract 2, add 5, subtract 2, . . . Next number is 24.
The series 1 6 10 13 15 (1+5=6; 6+4=10, 10+3=13; 13+2=15) is completed by 15+1=16. The answer is 16.

The pattern is - 5 then +2. 2 and 4 are the next numbers in the series.
49 (it is an arithmetic series that adds 5 then 7 then 9 then 11 then 13)
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 rule is: add 5, subtract 2, add 5, subtract 2, . . . Next number is 24.
The series 1 6 10 13 15 (1+5=6; 6+4=10, 10+3=13; 13+2=15) is completed by 15+1=16. The answer is 16.
This looks like a (subtract 5; add 2) series, so the next numbers are: 2, 4, -1, 1
24 for each number you add 5 and then subtract 2. 19 plus 5 is 24.
This is the series of square numbers, (16= 4*4). The next number is 5*5=25.
