24 for each number you add 5 and then subtract 2. 19 plus 5 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.
The rule is: add 5, subtract 2, add 5, subtract 2, . . . Next number is 24.
21-3=18 18/2=9 9*3=27 that is the pattern so after the 36 it should be 33
To determine the pattern in the series 13, 18, 16, 21, 19, we can observe that there are alternating increases and decreases by 5 and 3, respectively. Starting with 13, we add 5 to get 18, then subtract 2 to get 16, add 5 to get 21, and finally subtract 2 to get 19. Following this pattern, the next number would involve adding 5 to 19, resulting in 24.
