There are many possible answers.
One is the cubic function:
Un = (n3 - 9n2 + 44n - 6)/6 for n = 1, 2, 3, ...
5-30-6-42-7-56-8-72
If you mean: 2 5 11 23 47 then they are increasing by 3 6 12 24
More info would be nice but if you mean what is the fraction that indicates 12 of 15 it would be 4/5 ? of 15 as 4/5 * 15 = 60/5 or 12 & 5/5 * 15 = 75/5 or 15
The pattern rule for the given sequence is that each number is the sum of the previous number and a specific increment. In this case, the increment appears to be increasing by 1, then 2, then 3, then 4, and finally 5. So, the pattern rule can be expressed as: (n = n-1 + k), where (k) is the increment.
Given that: 12/3 = 4 15/3 = 5 12/15 = 4/5
multiplication pattern
The rule is 5, 10, 15 and so the next number will be 20+31 = 51
The pattern rule is: 4 5 6 7 8 and so the next number will be 33+9 = 42
5-30-6-42-7-56-8-72
255 ÷ 1 = 255 255 ÷ 3 = 85 255 ÷ 5 = 51 255 ÷ 15 = 17 255 ÷ 17 = 15 255 ÷ 51 = 5 255 ÷ 85 = 3 255 ÷ 255 = 1
It is: 3 6 12 24 48 .... double up each time
(12-15)/5 = -3/5
If you mean: 2 5 11 23 47 then they are increasing by 3 6 12 24
The rule is 10

3/5 = 9/15 and is not equal to 12/15
