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.

What is the next sequence 7 21 8 72 9?

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.

7 21 8 72 9 continue pattern?

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.
