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 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
The next number in the sequence 5-7-13-31 is 69.
-17, -21 Pattern is subtract 4.
Without a sequence given in the question, the next number to 6 is 7.
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
The next number in the sequence 5-7-13-31 is 69.
-17, -21 Pattern is subtract 4.
72/42 = 12/7
In fact, what are the next 2 numbers: 7, 14, 17, 21, 27, 28, 35, 37, ?, ? The next two numbers are 42 and 47. It's a set of numbers that contain or can be divided by 7.
