The sequence appears to alternate between two patterns. The first pattern consists of multiplying the previous number by 3 (7 to 21), and the second pattern involves simply increasing the last number by 1 (8 to 9). Following this logic, after 9, the next number should be (9 \times 8 = 72), leading us to conclude that the next number in the sequence is 10, which would continue the pattern. Thus, the next number is 10.
The pattern appears to alternate between two sequences: one sequence (7, 8, 9) increases by 1, while the other sequence (21, 72) seems to be multiplied by a factor. Specifically, 21 multiplied by 3 is 63, and 72 can be derived from 9 multiplied by 8. Following this pattern, the next number should be 10, and for the second sequence, multiplying 72 by 4 gives 288. So, the continuation of the pattern is 10, 288.
The sequence alternates between multiplying a number and then adding one. Starting with 7, multiplying by 3 gives 21, then adding 1 gives 8. Next, multiplying 8 by 9 gives 72, and adding 1 gives 9. Following this pattern, the next step would be to multiply 9 by 11, resulting in 99. Thus, the next number is 99.
3 can go into both these numbers 72/3= 24 21/3= 7
-17, -21 Pattern is subtract 4.
The next number in the sequence 5-7-13-31 is 69.
7, 21, 8, 72, 9, ?

243 is one possibility.
They are a sequence of odd numbers. The next three in the sequence would be 17,19 & 21
72
(98) = 2 * (49) = 7 * 7 ( both primes, end sequence) so > prime factors are : 21 * 72
21
3 can go into both these numbers 72/3= 24 21/3= 7
-17, -21 Pattern is subtract 4.
72/42 = 12/7
The next number in the sequence 5-7-13-31 is 69.
