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.
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.
The common denominator is 72, so 5/18 = 20/72, and 7/24 = 21/72. Now you can subtract the numerators [20-21 = -1]. So the answer is -1/72.
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
The next number in the sequence 5-7-13-31 is 69.
3 can go into both these numbers 72/3= 24 21/3= 7
-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.
