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.
the answer will be 21
26. for the pattern: add 10, subtract 5, add 10, subtract 5, ...the series is given as x+10-5so here16+10= 26-5=21+10=31-5=26so next no. is 26262626
The Greatest Common Factor of 9, 18, 21: 3
21 over 10 as a mixed number is 21/10
The divisors of 21 are: 1, 3, 7, 21.
21
24
24, they are going up in 3's, 13, 16, 19 and 18, 21 so 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
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.
24 for each number you add 5 and then subtract 2. 19 plus 5 is 24.
The next number is -21
24
291
the answer will be 21
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.
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).
